Subject: [PATCH v1 06/10] gpio: pca953x: Utilise temporary variable for struct device
Date: Fri, 1 Sep 2023 16:40:37 +0300 [thread overview]
Message-ID: <20230901134041.1165562-6-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230901134041.1165562-1-andriy.shevchenko@linux.intel.com>
We have a temporary variable to keep pointer to struct device.
Utilise it where it makes sense.
