From 295bb01e2666e450be7f6e6e1f5785bfb26fd60e Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 6 Jan 2015 15:11:13 +0200 Subject: [PATCH] arm: macro whitespace fixes While working on arch/arm/include/asm/uaccess.h, I noticed that some macros within this header are made harder to read because they violate a coding style rule: space is missing after comma. Fix it up. Signed-off-by: Michael S.
