Subject: tty: sc16is7xx: remove retval from gpiochip_remove()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e27e278608d0dca1b97abea3c1855beafcc68bcb;p=deliverable%2Flinux.git

tty: sc16is7xx: remove retval from gpiochip_remove()

We are trying to smoke out the use of the return value from
gpiochip_remove() from the kernel, this has been missed.
