CVE-2022-50340
media: vimc: Fix wrong function called when vimc_init() fails
In the Linux kernel, the following vulnerability has been resolved:
media: vimc: Fix wrong function called when vimc_init() fails
In vimc_init(), when platform_driver_register(&vimc_pdrv) fails,
platform_driver_unregister(&vimc_pdrv) is wrongly called rather than
platform_device_unregister(&vimc_pdev), which causes kernel warning:
Unexpected driver unregister!
WARNING: CPU: 1 PID: 14517 at drivers/base/driver.c:270 driver_unregister+0x8f/0xb0
