Peter Huewe 0b0595bfda Staging: Panel: prevent driver from calling misc_deregister twice on same ressource 
This patch prevents the driver from calling misc_deregister twice on the same
ressouce when unloading the driver.
Unloading the driver without this patch results in a Kernel BUG like this:
Panel driver version 0.9.5 registered on parport0 (io=0x378).
BUG: unable to handle kernel paging request at 0000000000100108
IP: [<ffffffff803c02ee>] misc_deregister+0x2d/0x90
PGD 6caff067 PUD 762b7067 PMD 0
Oops: 0002 [#1] PREEMPT SMP
last sysfs file: /sys/devices/platform/w83627hf.656/in8_input
...

This patch fixes this issue, although maybe not in the best way possible :)
