Subject: Re: [PATCH 1/9] pinctrl: qcom: ssbi-gpio: hardcode IRQ counts

Hi Brian!

I found a second bug in this patch:

Do not lose this assignment of pctrl->npins.

pctrl->npins is used further down in the code and the gpiochip
does not probe because of zero pins. You could
get rid of the local variable npins and just use pctrl->npins
everywhere though.

Yours,
