gpio: pca953x: disable regmap locking for automatic address incrementing
commitec3decd213
upstream. It's a repetition of the commitaa58a21ae3
("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. Fixes:bcf41dc480
