We can not make the assumption that the bound subdev is always a CSI mux, in i.MX6UL/i.MX6ULL that is not the case. So, just get the entity selected by source directly upstream from the CSI.

5 daysmedia: imx7: csi: Fix regression for parallel cameras on i.MX6ULFabio Estevam1-6/+6
Commit 86e02d07871c ("media: imx5/6/7: csi: Mark a bound video mux as a CSI mux") made an incorrect assumption that for imx7-media-csi, the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there is no CSI mux at all, so do not return an error when the entity is not a video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when appropriate. This is the same approach as done in imx-media-csi.c and it fixes the csi probe regression on i.MX6UL. Tested on a imx6ull-evk board.

5 daysmedia: ccs: Make (non-)use of uninitialised variables more robustSakari Ailus1-4/+20
GCC with W=2 level of kernel compiler warnings warns about the use of uninitialised variables in a few locations. While these uninitialised variables were not used in reality, this still produced compiler warnings. Address this by assigning the variables to NULL and checking for NULL in places it is not expected, returning -EIO in that case. This provides at least some sanity checking at runtime as the compiler appears unable to do that at compile time.

Currently we rely on firmware to return error when we reach the maximum supported number of sessions. But this errors are happened at reqbuf time which is a bit later.

7 daysmedia: venus: preserve DRC state across seeksAlexandre Courbot1-2/+9
DRC events can happen virtually at anytime, including when we are starting a seek. Should this happen, we must make sure to return to the DRC state, otherwise the firmware will expect buffers of the new resolution whereas userspace will still work with the old one. Returning to the DRC state upon resume for seeking makes sure that the client will get the DRC event and will reallocate the buffers to fit the firmware's expectations.

7 daysmedia: venus: use contig vb2 opsAlexandre Courbot4-14/+9
This driver uses the SG vb2 ops, but effectively only ever accesses the first entry of the SG table, indicating that it expects a flat layout. Switch it to use the contiguous ops to make sure this expected invariant is always enforced. Since the device is supposed to be behind an IOMMU this should have little to none practical consequences beyond making the driver not rely on a particular behavior of the SG implementation.

7 daysmedia: em28xx: Fix use-after-free in em28xx_alloc_urbsDinghao Liu1-5/+1
When kzalloc() fails, em28xx_uninit_usb_xfer() will free usb_bufs->buf and set it to NULL. Thus the later access to usb_bufs->buf[i] will lead to null pointer dereference. Also the kfree(usb_bufs->buf) after that is redundant.
