Subject: [PATCH v2 26/40] arch/sparc: uaccess_64 macro whitespace fixes
Date: Tue, 6 Jan 2015 17:44:56 +0200 [thread overview]
Message-ID: <1420558883-10131-27-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1420558883-10131-1-git-send-email-mst@redhat.com>
Macros within arch/sparc/include/asm/uaccess_64.h are made harder to
read because they violate a bunch of coding style rules.
Fix it up.
