[PATCH 1/2] pinctrl: cs42l43: Fix leaked pm reference on error path

[Charles Keepax]

Returning directly if the regmap_update_bits() fails causes a pm runtime
reference to be leaked, let things run to the end of the function
instead.

[PATCH 2/2] pinctrl: cs42l43: Fix polarity on debounce

[Charles Keepax]

The debounce bit sets a bypass on the debounce rather than enabling it,
as such the current polarity of the debounce is set incorrectly. Invert
the polarity to correct this.
