Subject: [PATCH 3/3] ARM: spinlock: use unified assembler language syntax
Date: Sun, 30 Dec 2018 17:08:19 +0100 [thread overview]
Message-ID: <088ecb1e526e3ccfd58dd3f7cae8a98edd23008c.1546185298.git.stefan@agner.ch> (raw)
In-Reply-To: <cover.1546185298.git.stefan@agner.ch>
Convert the conditional infix to a postfix to make sure this inline
assembly is unified syntax.
