[PATCH] prevent dmesg warning in zr36067 driver
Fix the warning "Debug: sleeping function called from invalid context at
include/asm/semaphore.h:102" that the zr36067 driver emits every time an
application using JPEG capture starts up (e.g. mjpegtools' lavrec).
The warning is harmless, but clogs up the dmesg output. This was logged as
bugzilla #5403. (Thanks to Christian Casteyde for helping me in fixing
this long-standing annoyance.)
