Subject: [PATCH v3 1/6] serial: core: Switch to use DEVICE_ATTR_RO()
Date: Mon, 17 Feb 2020 13:40:11 +0200 [thread overview]
Message-ID: <20200217114016.49856-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200217114016.49856-1-andriy.shevchenko@linux.intel.com>
Move device attributes to DEVICE_ATTR_RO() as that would make things
a lot more "obvious" what is happening here.
Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
