From ec3decd21380081e3b5de4ba8d85d90a95f201a0 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 5 Jun 2020 16:40:36 +0300 Subject: [PATCH] gpio: pca953x: disable regmap locking for automatic address incrementing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It's a repetition of the commit aa58a21ae378 ("gpio: pca953x: disable regmap locking") which states the following: 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.
