From f23487cdbe3bd002e99f41250143014e522c34de Mon Sep 17 00:00:00 2001 From: Anshul Garg Date: Wed, 8 Jul 2015 16:41:39 -0700 Subject: [PATCH] Input: joydev - use for_each_set_bit where appropriate Use for_each_set_bit to check for set bits in bitmap as it is more efficient than checking individual bits.
