[PATCH 3.16 219/294] gpio: drop retval check enforcing from gpiochip_remove()

From: Ben Hutchings
Date: Mon Nov 06 2017 - 20:17:47 EST


3.16.50-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

commit 14c8a620ba436511b1347c592633befa49535176 upstream.

As we start to decomission the return value from gpiochip_remove()
the compilers emit warnings due to the function being tagged
__must_check. So drop this until we remove the return value
altogether.
