+Subject: arm64: dts: lx2160a-cex7/lx2162a-sr-som: fix usd-cd & gpio pinmux
+
+From: Josua Mayer <josua@solid-run.com>
+
+commit 70008aee892bbb5c2969bbe9e5778fc081b14bd2 upstream.
+
+Commit 8a1365c7bbc1 ("arm64: dts: lx2160a: add pinmux and i2c gpio to
+support bus recovery") introduced pinmux nodes for lx2160 i2c
+interfaces, allowing runtime change between i2c and gpio functions
+implementing bus recovery.
+
+However, the dynamic configuration area (overwrite MUX) used by the
+pinctrl-single driver initially reads as zero and does not reflect the
+actual hardware state set by the Reset Configuration Word (RCW) at
+power-on.
+
+Because multiple groups of pins are configured from a single 32-bit
+register, the first write from the pinctrl driver unintentionally clears
+all other bits to zero.
+
+For example, on the LX2162A Clearfog, RCWSR12 is initialized to
+0x08000006. When any i2c pinmux is applied, it clears all other fields.
+This inadvertently disables SD card-detect (IIC2_PMUX) and some GPIOs
+(SDHC1_DIR_PMUX):
+
+LX2162-CF RCWSR12: 0b0000100000000000 0000000000000110
+IIC2_PMUX ||| ||| || | ||| |||XXX : I2C/GPIO/CD-WP
+SDHC1_DIR_PMUX XXX ||| || | ||| ||| : SDHC/GPIO/SPI
+
+Reverting the commit in question was considered but bus recovery is an
+important feature.
+
+Instead add pinmux nodes for those pins that were unintentionally
+reconfigured on SolidRun LX2160A Clearfog-CX and LX2162A Clearfog
+boards.

+Subject: HID: playstation: Clamp num_touch_reports
+
+From: T.J. Mercier <tjmercier@google.com>
+
+commit cac61b58a3b6340c52afa06bb15eac033158db2f upstream.
+
+A device would never lie about the number of touch reports would it?
+
+If it does the loop in dualshock4_parse_report will read off the end of
+the touch_reports array, up to about 2 KiB for the maximum number of 256
+loop iteraions. The data that is read is emitted via evdev if the
+DS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by
+clamping the num_touch_reports value provided by the device to the
+maximum size of the touch_reports array.
+
+Fixes: 752038248808 ("HID: playstation: add DualShock4 touchpad support.")

+Subject: media: i2c: imx283: Enter full standby when stopping streaming
+
+From: Jai Luthra <jai.luthra@ideasonboard.com>
+
+commit bce1349dbf6348ddee47308e2ed08878356de317 upstream.
+
+Use IMX283_STANDBY (bit 0) instead of IMX283_STBLOGIC (bit 1) when
+stopping streaming. STBLOGIC only puts the sensor logic into standby but
+leaves the MIPI interface (along with other components) in an
+indeterminate state.
+
+This (presumably) causes the CSI receiver (e.g. Raspberry Pi's CFE) to
+miss the LP-11 to HS transition when streaming restarts, resulting in a
+hang of 10+ seconds. The issue is most visible when immediately
+restarting a full-resolution stream after stopping a 3x3 binned one, so
+that runtime suspend hasn't yet been triggered.
+
+Writing IMX283_STANDBY puts the entire sensor into standby. The
+imx283_standby_cancel() sequence already handles the full wakeup from
+this suspended state.

+Subject: media: i2c: imx283: Fix hang when going from large to small resolution
+
+From: Jai Luthra <jai.luthra@ideasonboard.com>
+
+commit 9206359b2c396ff594adf39bc7daaadab0fcb367 upstream.
+
+When switching between modes (e.g. full resolution to binned),
+standby_cancel() previously cleared XMSTA (starting master mode data
+output) before the new mode's MDSEL, crop, and timing registers were
+programmed in start_streaming(). This caused the sensor to briefly
+output MIPI data using the previous mode's configuration.
+
+On receivers like imx-mipi-csis, this leads to FIFO overflow errors
+when switching from a higher to a lower resolution, as the receiver is
+configured for the new smaller frame size but receives stale
+full-resolution data.
+
+Fix this by moving the XMSTA and SYNCDRV register writes from
+standby_cancel() to the end of start_streaming(), after all mode,
+crop, and timing registers have been configured. Also explicitly stop
+master mode (XMSTA=1) when stopping the stream, matching the pattern
+used by other Sony sensor drivers (imx290, imx415).
+
+Use named macros IMX283_XMSTA_START/STOP instead of raw 0/BIT(0) for
+readability.

+commit f75e160745663ce9b13362ae6e90bd439c58df69 upstream.
+
+The control handler wasn't freed if adding controls failed, add an error

+
+From: Ethan Tidmore <ethantidmore06@gmail.com>
+
+commit 8dd088b8b106f7b119664f965b691785998edcfb upstream.
+
+In a error path isp->psys is confirmed to be an error pointer not NULL so
+this condition is true and the error pointer is dereferenced. So isp-psys
+should be set to NULL before going to out_ipu6_bus_del_devices.
+
+Detected by Smatch:
+drivers/media/pci/intel/ipu6/ipu6.c:690 ipu6_pci_probe() error:
+'isp->psys' dereferencing possible ERR_PTR()

+
+From: Guoniu Zhou <guoniu.zhou@nxp.com>
+
+commit 2f38622d0f85f317be9e6b131da6cd511db94fd2 upstream.
+
+Fix a hang issue when capturing a single frame with applications like cam
+in libcamera. It would hang waiting for the driver to complete the buffer,
+but streaming never starts because min_queued_buffers was set to 2.
+
+The ISI module uses a ping-pong buffer mechanism that requires two buffers
+to be programmed at all times. However, when fewer than 2 user buffers are
+available, the driver use internal discard buffers to fill the remaining
+slot(s). Reduce minimum queued buffers from 2 to 0 allows streaming to
+start without any queued buffers.

+
+commit d51c60a498e83c9a79884c8e420f97e3885c9583 upstream.
+
+Add checks for ioremap return values in saa7164_dev_setup(). If
+ioremap for BAR0 or BAR2 fails, release the already allocated PCI
+memory regions, remove the device from the global list, decrement
+the device count, and return -ENODEV.
+
+This prevents potential null pointer dereferences and ensures proper
+cleanup on memory mapping failures.

+
+From: Ricardo Ribalda <ribalda@chromium.org>
+
+commit fbac03467e53d8d72e5099c03df26d9adae11416 upstream.
+
+The UVC driver has two video streams, one for the frames and another one
+for the metadata. Both streams share most of the codebase, but only the
+data stream declares support for DMABUF transfer mode.
+
+I have tried the DMABUF transfer mode with CONFIG_DMABUF_HEAPS_SYSTEM
+and the frames looked correct.
+
+This patch announces the support for DMABUF for the metadata stream.
+This is useful for apps/HALs that only want to support DMABUF.

+
+vb2_dma_contig sets VMA flags VM_DONTEXPAND and VM_DONTDUMP and I do not
+see a reason why vb2_dma_sg should behave differently. This avoids
+hitting `WARN_ON(!(vma->vm_flags & VM_DONTEXPAND));` in
+drm_gem_mmap_obj() during mmap() of an imported dma-buf from the out of
+tree Apple ISP camera capture driver which uses vb2_dma_sg_memops.

+There were discussions in [1] at the end of 2023 that mmap() on imported
+dma-bufs should not be supported but as of v6.17 drm_gem_shmem_mmap() in
+drm_gem_shmem_helper.c still supports it.
+This might affect all gpu or accel drivers using drm_gem_shmem_mmap() or
+the wrapper drm_gem_shmem_object_mmap().

+From: Johan Hovold <johan@kernel.org>
+
+commit 0d15ce31375ccef4162f960b34547a821b7619d2 upstream.
+
+The driver reuses the OF node of the parent multi-function device but
+fails to take another reference to balance the one dropped by the
+platform bus code when unbinding the MFD and deregistering the child
+devices.
+
+Fix this by using the intended helper for reusing OF nodes.

+Subject: staging: media: atomisp: Disallow all private IOCTLs
+
+From: Sakari Ailus <sakari.ailus@linux.intel.com>
+
+commit 2b7eb2c5dc72f0fc954ac4aa155f9e285e937f7c upstream.
+
+Disallow all private IOCTLs. These aren't quite as safe as one could
+assume of IOCTL handlers; disable them for now. Instead of removing the
+code, return in the beginning of the function if cmd is non-zero in order
+to keep static checkers happy.
