Subject: realtek: fix RTL8231 gpio count
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=851212a71454735ebabf401d07845a642700e11e;p=openwrt%2Fstaging%2Fmkresin.git

realtek: fix RTL8231 gpio count

The RTL8231's gpio_chip.ngpio was set to 36, which is the largest valid
GPIO index. Fix the allowed number of GPIOs by setting ngpio to 37, the
actual line count.
