Subject: irq: Export per-cpu irq allocation and de-allocation functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aec2e2ad1786eb07814ae60988e0e306cd24a6cc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

irq: Export per-cpu irq allocation and de-allocation functions

Some drivers might use the per-cpu interrupts and still might be built as a
module. Export request_percpu_irq an free_percpu_irq to these user, which
also make it consistent with enable/disable_percpu_irq that were exported.
