The bit obtained by the function memory_bm_find_bit() is represented by addr and bit_nr. The callers of memory_bm_find_bit() just use addr and bit_nr as the arguments of set_bit/clear_bit/test_bit. This patch simplifies the representation of the obtained bit without using BM_BITS_PER_CHUNK. Signed-off-by: Akinobu Mita <akinobu.mita@xxxxxxxxx> Cc: Pavel Machek <pavel@xxxxxxx> Cc: Rafael J.
