+Subject: media: rc: streamzap: Error handling in probe
+
+From: Oliver Neukum <oneukum@suse.com>
+
+commit 42844992664f03ef9f930e64f7370fa481e9c267 upstream.
+
+If submitting the URB fails, the device will be unusable.
+Probe() must fail.

+
+commit e280d1e5e3f2595bbb43fe6e1bce00c59a43c0ff upstream.
+
+The buffer for IO must not be part of the device structure
+because that violates the DMA coherency rules.

+Subject: media: uvcvideo: Enable VB2_DMABUF for metadata stream
+
+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.

+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.

+
+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.
