Subject: [PATCH v2 33/40] cris: macro whitespace fixes
Date: Tue, 6 Jan 2015 17:45:21 +0200	[thread overview]
Message-ID: <1420558883-10131-34-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1420558883-10131-1-git-send-email-mst@redhat.com>

While working on arch/cris/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.
