Subject: [PATCH 5.2 01/37] gpio: pca953x: correct type of reg_direction

From: David Jander <david@...tonic.nl>

commit bc624a06f0c5190bc37fec7d22cd82b43a579698 upstream.

The type of reg_direction needs to match the type of the regmap, which
is u8.

Fixes: 0f25fda840a9 ("gpio: pca953x: Zap ad-hoc reg_direction cache")
