From 2f39f68cec0a19c0371c1e7cb149159810e87f64 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 10 May 2021 12:50:32 +0300 Subject: leds: lm3532: Make error handling more robust It's easy to miss necessary clean up, e.g. firmware node reference counting, during error path in ->probe(). Make it more robust by moving to a single point of return.
