From 47203198ed3df0f6896d07613182c05cb94110a5 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 31 Jan 2020 20:29:18 +0800 Subject: [PATCH] gpio: wcd934x: Fix logic of wcd_gpio_get The check with register value and mask should be & rather than &&. While at it, also use "unsigned int" for value variable because regmap_read() takes unsigned int *val argument.
