Thanks for reporting this issue. You most likely don't need the M-5MOLS
camera sensor driver on you system so one option is to just disable it
at kernel config. Make sure CONFIG_VIDEO_M5MOLS is not set, it can be
unselected at menuconfig
-> Device Drivers
-> Multimedia
-> Encoders, decoders, sensors and other helper chips

The below patch which is intended to fix this issue won't work for
media drivers backport builds on kernels older than 3.6, so m5mols
driver should not be built for kernel versions < 3.6.

Subject: [PATCH] m5mols: Add missing #include <linux/sizes.h>
Include <linux/sizes.h> header that is missing after commit ab7ef22419927
"[media] m5mols: Implement .get_frame_desc subdev callback".
It prevents possible build errors due to undefined SZ_1M.
