From b97760ae8e3dc8bb91881c13425a0bff55f2bd85 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 10 Sep 2018 11:37:45 +0300 Subject: pinctrl: at91-pio4: fix has_config check in atmel_pctl_dt_subnode_to_map() Smatch complains about this condition: if (has_config && num_pins >= 1) The "has_config" variable is either uninitialized or true. The "num_pins" variable is unsigned and we verified that it is non-zero on the lines before so we know "num_pines >= 1" is true. Really, we could just check "num_configs" directly and remove the "has_config" variable.
