Subject: [PATCH 12/22] platform/chrome: cros_typec_switch: Use dev_err_probe()
Date: Fri,  9 Feb 2024 23:09:23 -0800	[thread overview]
Message-ID: <20240210070934.2549994-13-swboyd@chromium.org> (raw)
In-Reply-To: <20240210070934.2549994-1-swboyd@chromium.org>

Use dev_err_probe() helper so we can get better diagnostics when driver
probes fails for any reason.
