Subject: pinctrl: sunxi: Fix irq_of_xlate for the r_pio pinctrl block
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8297992cad599e8a214e65959ccdde51738fe5a2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: sunxi: Fix irq_of_xlate for the r_pio pinctrl block

The r_pio gpio / pin controller has a pin_base of non 0, we need to
adjust for this before calling sunxi_pinctrl_desc_find_function_by_pin.
