From f721bb0dbd3fd37f16c49c97155f40f22496a970 Mon Sep 17 00:00:00 2001 From: Akhil Bhansali Date: Wed, 23 Oct 2013 13:00:08 +0100 Subject: [PATCH] skd: Fix checkpatch ERRORS and removed unused functions This patch fixes checkpatch.pl errors for assignment in if condition. It also removes unused readq / readl function calls. As Andrew had disabled the compilation of drivers for 32 bit, I have modified format specifiers in few VPRINTKs to avoid warnings during 64 bit compilation.
