[PATCH] pinctrl/qcom: Fix -Wimplicit-fallthrough

[PATCH] pinctrl/qcom: Fix -Wimplicit-fallthrough

[Alex Dewar]

In pinctrl-spmi-gpio.c there is a switch case which is obviously
intended to fall through to the next label. Add a comment to suppress
-Wimplicit-fallthrough warning.

Thanks for your patch Alex, this was fixed in 6161dc03587b ("pinctrl:
qcom: spmi-gpio: Mark expected switch fall-through")
