X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=673aeb76d07f49f2b07792f813bc2a9fee212ab7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [POWERPC] Avoid calling get_irq_server() with a real, not virtual irq. We can use default_server when masking an interrupt vector. get_irq_server() assumes a virtual irq, so badness may happen if we give it a real one.
