From 24a66618d63548e1012bf65ed30a3c031f410ca2 Mon Sep 17 00:00:00 2001 From: "Ivan T. Ivanov" Date: Thu, 9 Apr 2015 18:18:36 +0300 Subject: [PATCH] pinctrl: qcom-spmi-gpio: Fix input value report Read input buffer when input is enabled, not when it is disabled. Also fix interpretation of the pmic_gpio_read() return code, negative value means an error. Signed-off-by: Ivan T.
