Subject: Revert "yenta free_irq on suspend"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=889371f61fd5bb914d0331268f12432590cf7e85;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Revert "yenta free_irq on suspend"

ACPI is wrong.  Devices should not release their IRQ's on suspend and
re-aquire them on resume.  ACPI should just re-init the IRQ controller
instead of breaking most drivers very subtly.

Breakage reported by Hugh Dickins <hugh@veritas.com>
