Subject: Input: joydev - use for_each_set_bit where appropriate
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f23487cdbe3bd002e99f41250143014e522c34de;p=openwrt%2Fstaging%2Fblogic.git

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.
