video: fbdev: fsl-diu-fb: mark expected switch fall-throughs

Fix the following warnings (Building: mpc512x_defconfig powerpc): drivers/video/fbdev/fsl-diu-fb.c: In function ‘fsl_diu_ioctl’: ./include/linux/device.h:1750:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/video/fbdev/fsl-diu-fb.c:1287:3: note: in expansion of macro ‘dev_warn’ dev_warn(info->dev, ^~~~~~~~ drivers/video/fbdev/fsl-diu-fb.c:1290:2: note: here case MFB_SET_PIXFMT: ^~~~ In file included from ./include/linux/acpi.h:15:0, from ./include/linux/i2c.h:13, from ./include/uapi/linux/fb.h:6, from ./include/linux/fb.h:6, from drivers/video/fbdev/fsl-diu-fb.c:20: ./include/linux/device.h:1750:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/video/fbdev/fsl-diu-fb.c:1296:3: note: in expansion of macro ‘dev_warn’ dev_warn(info->dev, ^~~~~~~~ drivers/video/fbdev/fsl-diu-fb.c:1299:2: note: here case MFB_GET_PIXFMT: ^~~~ Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Gustavo A.
