Subject: omap: GPIO: fix auto-disable of debounce clock
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7ec0b0b16c97a75a1b6aa8bc8b32548003f3339;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

omap: GPIO: fix auto-disable of debounce clock

The addition of the new debounce code (commit
168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of
debounce clocks on idle by forgetting to update the debounce clock
enable mask.

Add back the updating of bank->dbck_enable_mask so debounce clocks are
auto-disabled.
