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!
