From bae94dc39e9530842379208c4406512d34dc7ef3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 7 Oct 2010 03:33:00 -0300 Subject: [PATCH] [media] cx231xx-417: Fix a gcc warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gcc didn't like to have i++ inside a complex operation: drivers/media/video/cx231xx/cx231xx-417.c: In function ‘cx231xx_load_firmware’: drivers/media/video/cx231xx/cx231xx-417.c:1059: warning: operation on ‘i’ may be undefined drivers/media/video/cx231xx/cx231xx-417.c:1061: warning: operation on ‘i’ may be undefined drivers/media/video/cx231xx/cx231xx-417.c:1063: warning: operation on ‘i’ may be undefined Btw, I agree with gcc, as we're using i and i++ at the same operation and, depending on how optimization may occur, it may produce a wrong code. While here, fix CodingStyle issues on the changed code.
