Subject: [PATCH] staging: fbtft: Don't spam logs when probe is deferred
Git-commit: 37667f6e57712cef5652fa67f1cbd1299e204d94
Patch-mainline: v5.14-rc1
References: git-fixes
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().
Fixes: c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor interface")
