Subject[PATCH 1/3] regulator: max8973: get rid of extra variable for gpio validity
Date
To find that dvs-gpio is valid or not, gpio API gpio_is_valid()
can be directly used instead of intermediate variable.

Removing the extra variable and using the gpio_is_valid().

This is same as earlier patch. Making this as part of this series.
