The driver uses kzalloc and kfree functions. So it should include
linux/slab.h. This header file is implicitly included by v4l2-common.h
if CONFIG_SPI is enabled. But when it is disabled, slab.h is not
included. In this case, the driver does not compile:

This patch adds the missing include to fix this issue.
