Subject: [PATCH v6 07/12] thermal: qoriq: Convert driver to use devm_ioremap()
Date: Mon, 17 Jun 2019 09:14:53 -0700
Message-ID: <20190617161458.3754-8-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190617161458.3754-1-andrew.smirnov@gmail.com>

Convert driver to use devm_ioremap() to simplify memory deallocation
and error handling code. No functional change intended.
