Subject: Blackfin: do not error if GPIO IRQ is requested already as GPIO
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4b890b0cd9e0ac75cbdf7011ef38ebc662930e6;p=linux-beck.git

Blackfin: do not error if GPIO IRQ is requested already as GPIO

Some drivers expect to be able to request both as GPIO and GPIO IRQ, so
allow that use case.
