Subject: [PATCH 5.12 574/700] leds: lm3697: Dont spam logs when probe is deferred

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ Upstream commit 807553f8bf4afa673750e52905e0f9488179112f ]

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().
