2021-01-27media: uvcvideo: Force UVC version to 1.0a for 1bcf:0b40Laurent Pinchart2-0/+18
The Shenzhen Aoni Electronic Co.,Ltd 2K FHD camera reports a UVC 1.10 version, but implements UVC 1.0a as shown by the UVC probe control being 26 bytes long. Force the UVC version for that device.

2021-01-27media: zr364xx: fix memory leaks in probe()Dan Carpenter1-18/+31
Syzbot discovered that the probe error handling doesn't clean up the resources allocated in zr364xx_board_init(). There are several related bugs in this code so I have re-written the error handling. 1) Introduce a new function zr364xx_board_uninit() which cleans up the resources in zr364xx_board_init(). 2) In zr364xx_board_init() if the call to zr364xx_start_readpipe() fails then release the "cam->buffer.frame[i].lpvbits" memory before returning. This way every function either allocates everything successfully or it cleans up after itself. 3) Re-write the probe function so that each failure path goto frees the most recent allocation. That way we don't free anything before it has been allocated and we can also verify that everything is freed. 4) Originally, in the probe function the "cam->v4l2_dev.release" pointer was set to "zr364xx_release" near the start but I moved that assignment to the end, after everything had succeeded. The release function was never actually called during the probe cleanup process, but with this change I wanted to make it clear that we don't want to call zr364xx_release() until everything is allocated successfully. Next I re-wrote the zr364xx_release() function. Ideally this would have been a simple matter of copy and pasting the cleanup code from probe and adding an additional call to video_unregister_device(). But there are a couple quirks to note. 1) The probe function does not call videobuf_mmap_free() and I don't know where the videobuf_mmap is allocated. I left the code as-is to avoid introducing a bug in code I don't understand. 2) The zr364xx_board_uninit() has a call to zr364xx_stop_readpipe() which is a change from the original behavior with regards to unloading the driver. Calling zr364xx_stop_readpipe() on a stopped pipe is not a problem so this is safe and is potentially a bugfix.

2021-01-27media: smipcie: switch from 'pci_' to 'dma_' APIChristophe JAILLET1-11/+15
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'smi_port_init()' GFP_KERNEL can be used because this function is called only from the probe function and no lock is taken in between.

Commit 3d1387b3b8f6 ("media: vidtv: fix some warnings") replaced the unused flexible array member at the end of struct vidtv_mpeg_ts with a pointer. This broke the 188-byte alignment since the struct no longer was 4 bytes in size. Fix this by removing this field entirely.
