From 61dd8365bf442a5c07955ef4b1fd665f8c3aadb4 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sat, 5 Dec 2020 18:02:32 +0100 Subject: azalia: Make `set_bits` function non-static There's many copies of this function in the tree. Make the copy in azalia_device.c non-static and rename it to `azalia_set_bits`, then replace all other copies with it. Since azalia_device.c is only built when AZALIA_PLUGIN_SUPPORT is selected, select it where necessary. This has the side-effect of building hda_verb.c from the mainboard directory. If this patch happens to break audio on a mainboard, it's because its hda_verb.c was always wrong but wasn't being compiled.
