In the Linux kernel, the following vulnerability has been resolved:

media: pci: cx23885: Fix the error handling in cx23885_initdev()

When the driver fails to call the dma_set_mask(), the driver will get
the following splat:

[   55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240
[   55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590
[   55.856822] Call Trace:
[   55.860327]  __process_removed_driver+0x3c/0x240
[   55.861347]  bus_for_each_dev+0x102/0x160
[   55.861681]  i2c_del_driver+0x2f/0x50

This is because the driver has initialized the i2c related resources
in cx23885_dev_setup() but not released them in error handling, fix this
bug by modifying the error path that jumps after failing to call the
dma_set_mask().
