Subject: [PATCH AUTOSEL 5.19 15/29] ALSA: hda/hdmi: Fix the converter reuse for the silent stream
Date: Sun, 2 Oct 2022 18:49:08 -0400 [thread overview]
Message-ID: <20221002224922.238837-15-sashal@kernel.org> (raw)
In-Reply-To: <20221002224922.238837-1-sashal@kernel.org>
From: Jaroslav Kysela <perex@perex.cz>
[ Upstream commit 5f80d6bd2b01de4cafac3302f58456bf860322fc ]
When the user space pcm stream uses the silent stream converter,
it is no longer allocated for the silent stream. Clear the appropriate
flag in the hdmi_pcm_open() function. The silent stream setup may
be applied in hdmi_pcm_close() (and the error path - open fcn) again.
If the flag is not cleared, the reuse conditions for the silent
stream converter in hdmi_choose_cvt() may improperly share
this converter.
