From: Anshul Garg Date: Thu, 9 Jul 2015 17:18:22 +0000 (-0700) Subject: Input: uinput - switch to using for_each_set_bit() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b6d30968d86c45a7bb599eaca13ff048d3fa576c;p=linux-beck.git Input: uinput - switch to using for_each_set_bit() Use for_each_set_bit to check for set bits in bitmap as it is more efficient and compact.
