From e458d3f39d917770cef2ed78891349362ecd3e15 Mon Sep 17 00:00:00 2001 From: Anand Moon Date: Sat, 25 Sep 2021 17:34:12 +0000 Subject: [PATCH] regulator: pwm-regulator: Make use of the helper function dev_err_probe() devm_pwm_get() can return -EPROBE_DEFER if the pwm regulator is not ready yet. Use dev_err_probe() for pwm regulator resources to indicate the deferral reason when waiting for the resource to come up.
