Thadeu Lima de Souza Cascardo 1f2f38d89d drivers/char/misc.c: use bitmap/bitops functions for dynamic minor number allocation 
Use DECLARE_BITMAP(), find_first_zero_bit(), set_bit() and clear_bit()
instead of rewriting code to do it with the minor number dynamic
allocation bitmap.

We need to invert the bit position to keep the code behaviour of using the
last minor numbers first, since we don't have a find_last_zero_bit.
