From 18d43c9b88eb335440c5e769eb6c2d5bc908dc61 Mon Sep 17 00:00:00 2001 From: Keyon Jie Date: Tue, 11 Dec 2018 15:30:27 -0600 Subject: [PATCH] ALSA: HDA: export process_unsol_events() The SOF implementation does not rely on the hdac_bus library, however for HDMI and HDaudio codec support it does need to deal with unsolicited events. Instead of re-inventing the wheel, export this symbol to reuse this part of the library directly.
