From b9762e7b774c5849f694693fcd17cba0e78f2629 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 6 Jan 2015 17:45:34 +0200 Subject: [PATCH] parisc: macro whitespace fixes While working on arch/parisc/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.
