Hi Greg,

After merging the staging tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

WARNING: drivers/staging/vc04_services/bcm2835-camera/bcm2835-v4l2.o(.data+0x0): Section mismatch in reference from the variable bcm2835_camera_driver to the function .init.text:bcm2835_mmal_probe()
The variable bcm2835_camera_driver references
the function __init bcm2835_mmal_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
