Subject: [PATCH v1 2/2] fbtft: Don't spam logs when probe is deferred
Date: Fri, 16 Apr 2021 15:31:17 +0300	[thread overview]
Message-ID: <20210416123117.4993-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210416123117.4993-1-andriy.shevchenko@linux.intel.com>

When requesting GPIO line the probe can be deferred.
In such case don't spam logs with an error message.
This can be achieved by switching to dev_err_probe().
