From 3362ded9cdf3d50d870510e73cd778775e21162f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 9 Sep 2010 16:37:50 -0700 Subject: [PATCH] drivers/mmc/host/imxmmc.c: adjust confusing if indentation Move the second if (reg & ...) test into the branch indicated by its indentation. The test was previously always executed after the if containing that branch, but it was always false unless the if branch was taken. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r disable braces4@ position p1,p2; statement S1,S2; @@ ( if (...) { ... } | if (...)
