Subject: sparc: in handler_irq() rename irq parameter to pil
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d4d1ec48c4b1568338931bf8e7833543b78ec9d5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

sparc: in handler_irq() rename irq parameter to pil

The generic irq support uses "irq" to identify the
virtual irq number. To avoid confusion rename the
argument to handler_irq() to pil to match the
name of the parameter in the PCR register.
