From 6fdeb6cbe1ef3bccd2c5e2b3427a06e9cda1efc2 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 20 Apr 2020 20:27:52 +0300 Subject: gpio: pca953x: drop unused parameters of pca953x_recalc_addr() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After the previous patch the two last parameters of pca953x_recalc_addr() are unused and so can be dropped.
