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 :) linux version v2.6.32-rc1 - linus git tree, Di 29.
