From: Joe Perches Date: Wed, 6 Aug 2014 23:11:03 +0000 (-0700) Subject: checkpatch: add an index variable for fixed lines X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=194f66fc9567367b3fa2dcbc1b87b091330ef186;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git checkpatch: add an index variable for fixed lines Make the fix code a bit easier to read. This should also start to allow an easier mechanism to insert/delete lines eventually too.
