From 1ec93b9b176b3c4e065c326ccf40458fcc01e6c0 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 25 Apr 2014 09:24:21 +0800 Subject: [PATCH] mfd: rdc321x: Fix off-by-one for ngpio setting The valid gpio is GPIO0 ~ GPIO58, so ngpio should be 59. This patch also renames RDC321X_MAX_GPIO to RDC321X_NUM_GPIO because it actually means the number of available GPIOs.
