From 21a1d41174a16c1bba8b43eb607ac031f31533ae Mon Sep 17 00:00:00 2001 From: Daniele Alessandrelli Date: Mon, 16 Mar 2015 23:53:37 +0100 Subject: [PATCH] ft1000-pcmcia: ft1000_hw.c: fix style issues not requiring code refactoring Fix all the trivial style issues (as reported by checkpatch.pl) not requiring code refactoring. A following patch is expected to fix the remaining issues by performing some code refactoring.
