Date: Mon, 11 Jan 2021 13:40:26 +0100 [thread overview]
Message-ID: <20210111124027.21586-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20210111124027.21586-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
This function can fail if regmap operations fail so check its return
value in probe().
