Subject: MIPS: Mark all but i8259 interrupts as no-probe.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24649c00ca334955ac7d8a79f5a7834fc7ea441d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: Mark all but i8259 interrupts as no-probe.

Use set_irq_noprobe() to mark all MIPS interrupts as non-probe.  Override that
default for i8259 interrupts.
