Subject: gpio: tangier: Use correct type for the IRQ chip data
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7d045025a24b6336d444d359bd4312f351d017f9;p=linux.git

gpio: tangier: Use correct type for the IRQ chip data

IRQ chip data contains a pointer to the GPIO chip. Luckily we have
the pointers the same, but strictly speaking it's not guaranteed.
Even though, still better to fix this.

Fixes: ccf6fd6dcc86 ("gpio: merrifield: Introduce GPIO driver to support Merrifield")
