Subject: [PATCH v2 1/5] gpio: pca953x: coding style fixes
Date: Wed, 7 Sep 2016 11:24:53 +0200 [thread overview]
Message-ID: <1473240297-19881-2-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1473240297-19881-1-git-send-email-bgolaszewski@baylibre.com>
pca953x_gpio_set_multiple() has some coding style issues that make it
harder to read. Tweak the code a bit.
