ASoC: tegra: Fix Master Volume Control

jonhunter · broonie · commit f9fd804aa0a3 · 2023-06-13T12:10:56.000+01:00
Commit 3ed2b54 ("ALSA: pcm: fix wait_time calculations") corrected the PCM wait_time calculations and in doing so reduced the calculated wait_time. This exposed an issue with the Tegra Master Volume Control (MVC) device where the reduced wait_time caused the MVC to fail. For now fix this by setting the default wait_time for Tegra to be 500ms.
