Subject: gpio: sysfs: use gpiod_is_equal() to compare GPIO descriptors
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=32ad0b9a17f9aa8dd9308feda671bda98b274d24;p=thirdparty%2Fkernel%2Flinux.git

gpio: sysfs: use gpiod_is_equal() to compare GPIO descriptors

We have a dedicated comparator for GPIO descriptors that performs
additional checks and hides the implementation detail of whether the
same GPIO can be associated with two separate struct gpio_desc objects.
Use it in sysfs code
