+Subject: dmaengine: at_hdmac: fix device leak on of_dma_xlate()
+
+From: Johan Hovold <johan@kernel.org>
+
+commit b9074b2d7a230b6e28caa23165e9d8bc0677d333 upstream.
+
+Make sure to drop the reference taken when looking up the DMA platform
+device during of_dma_xlate() when releasing channel resources.
+
+Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing
+put_device() call in at_dma_xlate()") fixed the leak in a couple of
+error paths but the reference is still leaking on successful allocation.
+
+Fixes: bbe89c8e3d59 ("at_hdmac: move to generic DMA binding")
+Fixes: 3832b78b3ec2 ("dmaengine: at_hdmac: add missing put_device() call in at_dma_xlate()")

+Subject: dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()
+
+From: Miaoqian Lin <linmq006@gmail.com>
+
+commit 3f747004bbd641131d9396d87b5d2d3d1e182728 upstream.
+
+Fix a memory leak in gpi_peripheral_config() where the original memory
+pointed to by gchan->config could be lost if krealloc() fails.
+
+The issue occurs when:
+1. gchan->config points to previously allocated memory
+2. krealloc() fails and returns NULL
+3. The function directly assigns NULL to gchan->config, losing the
+ reference to the original memory
+4. The original memory becomes unreachable and cannot be freed
+
+Fix this by using a temporary variable to hold the krealloc() result
+and only updating gchan->config when the allocation succeeds.
+
+Found via static analysis and code review.

+
+From: Biju Das <biju.das.jz@bp.renesas.com>
+
+commit 747213b08a1ab6a76e3e3b3e7a209cc1d402b5d0 upstream.
+
+After audio full duplex testing, playing the recorded file contains a few
+playback frames from the previous time. The rz_dmac_terminate_all() does
+not reset all the hardware descriptors queued previously, leading to the
+wrong descriptor being picked up during the next DMA transfer. Fix the
+above issue by resetting all the descriptor headers for a channel in
+rz_dmac_terminate_all() as rz_dmac_lmdesc_recycle() points to the proper
+descriptor header filled by the rz_dmac_prepare_descs_for_slave_sg().

+Subject: drm/amd: Clean up kfd node on surprise disconnect
+
+From: Mario Limonciello (AMD) <superm1@kernel.org>
+
+commit 28695ca09d326461f8078332aa01db516983e8a2 upstream.
+
+When an eGPU is unplugged the KFD topology should also be destroyed
+for that GPU. This never happens because the fini_sw callbacks never
+get to run. Run them manually before calling amdgpu_device_ip_fini_early()
+when a device has already been disconnected.
+
+This location is intentionally chosen to make sure that the kfd locking
+refcount doesn't get incremented unintentionally.

+Subject: drm/nouveau/disp/nv50-: Set lock_core in curs507a_prepare
+
+From: Lyude Paul <lyude@redhat.com>
+
+commit 9e9bc6be0fa0b6b6b73f4f831f3b77716d0a8d9e upstream.
+
+For a while, I've been seeing a strange issue where some (usually not all)
+of the display DMA channels will suddenly hang, particularly when there is
+a visible cursor on the screen that is being frequently updated, and
+especially when said cursor happens to go between two screens. While this
+brings back lovely memories of fixing Intel Skylake bugs, I would quite
+like to fix it :).
+
+It turns out the problem that's happening here is that we're managing to
+reach nv50_head_flush_set() in our atomic commit path without actually
+holding nv50_disp->mutex. This means that cursor updates happening in
+parallel (along with any other atomic updates that need to use the core
+channel) will race with eachother, which eventually causes us to corrupt
+the pushbuffer - leading to a plethora of various GSP errors, usually:
+
+ nouveau 0000:c1:00.0: gsp: Xid:56 CMDre 00000000 00000218 00102680 00000004 00800003
+ nouveau 0000:c1:00.0: gsp: Xid:56 CMDre 00000000 0000021c 00040509 00000004 00000001
+ nouveau 0000:c1:00.0: gsp: Xid:56 CMDre 00000000 00000000 00000000 00000001 00000001
+
+The reason this is happening is because generally we check whether we need
+to set nv50_atom->lock_core at the end of nv50_head_atomic_check().
+However, curs507a_prepare is called from the fb_prepare callback, which
+happens after the atomic check phase. As a result, this can lead to commits
+that both touch the core channel but also don't grab nv50_disp->mutex.
+
+So, fix this by making sure that we set nv50_atom->lock_core in
+cus507a_prepare().

+Subject: drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel
+
+From: Marek Vasut <marex@nabladev.com>
+
+commit 6ab3d4353bf75005eaa375677c9fed31148154d6 upstream.
+
+The connector type for the DataImage SCF0700C48GGU18 panel is missing and
+devm_drm_panel_bridge_add() requires connector type to be set. This leads
+to a warning and a backtrace in the kernel log and panel does not work:
+"
+WARNING: CPU: 3 PID: 38 at drivers/gpu/drm/bridge/panel.c:379 devm_drm_of_get_bridge+0xac/0xb8
+"
+The warning is triggered by a check for valid connector type in
+devm_drm_panel_bridge_add(). If there is no valid connector type
+set for a panel, the warning is printed and panel is not added.
+Fill in the missing connector type to fix the warning and make
+the panel operational once again.

+In vmw_compat_shader_add(), the return value check of vmw_shader_alloc()
