From aa58a21ae37894d456a2f91a37e9fd71ad4aa27e Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 7 Apr 2020 17:42:45 +0200 Subject: [PATCH] gpio: pca953x: disable regmap locking This driver uses its own locking but regmap silently uses a mutex for all operations too. Add the option to disable locking to the regmap config struct.
