From: Chad Williamson Date: Tue, 18 Jun 2013 03:32:04 +0000 (-0500) Subject: Staging: silicom: move assignments out of if conditions X-Git-Tag: next-20130619~23^2~1 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3f3c1fc9adf65cb31565e08803cd20b7016e8f76;p=karo-tx-linux.git Staging: silicom: move assignments out of if conditions Remove a bunch of assignments from if-statement conditions in bpctl_mod.c, resolving checkpatch.pl errors. (This isn't all of them, but the patch is getting rather long...)
