[PATCH AUTOSEL 5.15 01/10] ASoC: jack: allow multiple interrupt per gpio
From: Svyatoslav Ryhel clamor95@gmail.com
[ Upstream commit a2d4051b0bd6dffcd736888ae89a550d6f60b060 ]
This feature is required for coupled hp-mic quirk used by some Nvidia Tegra 3 based devices work properly.

This quirk is used for cases when there is GPIO which detects any type of 3.5 Jack insertion and actual type of jack is defined by other GPIO. 3.5 Jack GPIO generates interrupt and MIC GPIO indicates type of Jack only if 3.5 Jack GPIO is active.
