From f34b32745e2c9f85ee33b42e7a8cdaa1ee1c16a3 Mon Sep 17 00:00:00 2001 From: sheetal Date: Wed, 17 Dec 2025 18:55:24 +0530 Subject: [PATCH] ASoC: tegra: Revert fix for uninitialized flat cache warning in tegra210_ahub Commit 4d4021b0bbd1 ("ASoC: tegra: Fix uninitialized flat cache warning in tegra210_ahub") attempted to fix the uninitialized flat cache warning that is observed for the Tegra210 AHUB driver. However, the change broke various audio tests because an -EBUSY error is returned when accessing registers from cache before they are read from hardware. Revert this change for now, until a proper fix is available.
