Subject: pinctrl/nomadik: use zero as default irq_start
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=832b6cdf72fdc32cacba242a749402d28f4648f0;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

pinctrl/nomadik: use zero as default irq_start

The irqdomain semantics were supposed to be such that a linear
domain would be used if the passed first_irq was zero or
negative, but I got it wrong so only passing zero as first_irq
will work properly. Well, zero is NO_IRQ these days so let's
pass zero. The semantics of irqdomain_add_simple() will be
fixed in a separate patch.
