Subject: [PATCH v2 4/5] gpio: pca953x: remove an unused variable
Date: Wed, 7 Sep 2016 11:24:56 +0200 [thread overview]
Message-ID: <1473240297-19881-5-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1473240297-19881-1-git-send-email-bgolaszewski@baylibre.com>
The chip_type variable in struct pca953x_chip is no longer required.
Remove it.
