I ran into a randconfig build error with the new driver: drivers/media/platform/cadence/cdns-csi2tx.c: In function 'csi2tx_probe': drivers/media/platform/cadence/cdns-csi2tx.c:477:11: error: implicit declaration of function 'kzalloc'; did you mean 'd_alloc'? [-Werror=implicit-function-declaration] kzalloc() is declared in linux/slab.h, so let's include this to make it build in all configurations.
