From d7e47e32192bb88f5b2dc8e655fa587ecf9d71e0 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sat, 9 Sep 2023 05:02:37 -0700 Subject: [PATCH] ASoC: wm8960: Fix error handling in probe Commit 422f10adc3eb ("ASoC: wm8960: Add support for the power supplies") added regulator support to the wm8960 driver, but neglected to update error handling in the probe function. This results in warning backtraces if the probe function fails.
