pinctrl: rockchip: Mark expected switch fall-through
When fall-through warnings was enabled by default the following warning
was starting to show up:
../drivers/pinctrl/pinctrl-rockchip.c: In function ‘rockchip_gpio_set_config’:
../drivers/pinctrl/pinctrl-rockchip.c:2783:3: warning: this statement may fall
through [-Wimplicit-fallthrough=]
rockchip_gpio_set_debounce(gc, offset, true);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../drivers/pinctrl/pinctrl-rockchip.c:2795:2: note: here
default:
^~~~~~~
Rework so that the compiler doesn't warn about fall-through. Add
'return -ENOTSUPP;' to match the comment.
Fixes: d93512ef0f0e ("Makefile: Globally enable fall-through warning")
