Subject[PATCH 12/17] gpio: gpiolib.c: fix a doc warning
Date
Use a different markup for the ERR_PTR, as %FOO doesn't work
if there are parenthesis. So, use, instead:

``ERR_PTR(-EINVAL)``

This fixes the following warning:

./drivers/gpio/gpiolib.c:139: WARNING: Inline literal start-string without end-string.
