[PATCH 1/4] pinctrl: single: Remove unreachable code

[Andrew Goodbody]

In single_read there is a switch block with a default label. All cases
in the switch block, including the default, return directly. So any code
following the switch block is unreachable. Remove the unreachable code.

This issue was found by Smatch.
