drivers/char/misc.c: clear allocation bit in minor bitmap when device register fails
If there's a failure creating the device (because there's already one with the same name, for example), the current implementation does not clear the bit for the allocated minor and that number is lost for future allocations. Second, the test currently in misc_deregister is broken, since it does not test for the 0 minor. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Cc: "H.
