Subject: [PATCH v1 3/3] PM / sysfs: Convert to use DEVICE_ATTR_RO / DEVICE_ATTR_RW
Date: Fri, 10 Nov 2017 20:28:09 +0200 [thread overview]
Message-ID: <20171110182809.85953-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20171110182809.85953-1-andriy.shevchenko@linux.intel.com>
Use DEVICE_ATTR_RO() and DEVICE_ATTR_RW() macros instead of
open coding them.
No functional change intended.
