Signed-off-by: Noralf Trønnes <noralf@tronnes.org> char: vc_mem: Fix up compat ioctls for 64bit kernel compat_ioctl wasn't defined, so 32bit user/64bit kernel always failed. VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size unsigned long, so the ioctl cmd changes between sizes. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org> char: vc_mem: Fix all coding style issues. Cleans up all checkpatch errors in vc_mem.c and vc_mem.h No functional change to the code.
