drm/i915: Preserve crtc_state->inherited during state clearing
stable inclusion from stable-v5.10.177 commit 4ede0da36c2fcd1f315c93719d9f3b7c7a807512 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I88YNP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4ede0da36c2fcd1f315c93719d9f3b7c7a807512 -------------------------------- commit 3a84f2c6 upstream. intel_crtc_prepare_cleared_state() is unintentionally losing the "inherited" flag. This will happen if intel_initial_commit() is forced to go through the full modeset calculations for whatever reason. Afterwards the first real commit from userspace will not get forced to the full modeset path, and thus eg. audio state may not get recomputed properly. So if the monitor was already enabled during boot audio will not work until userspace itself does an explicit full modeset.
