Subject: [PATCH 5.15 443/846] ALSA: hda/cs8409: Increase delay during jack detection

From: Christian A. Ehrhardt <lk@...e.de>

[ Upstream commit 8cd07657177006b67cc1610e4466cc75ad781c05 ]

Commit c8b4f0865e82 reduced delays related to cs42l42 jack
detection. However, the change was too aggressive. As a result
internal speakers on DELL Inspirion 3501 are not detected.

Increase the delay in cs42l42_run_jack_detect() a bit.

Fixes: c8b4f0865e82 ("ALSA: hda/cs8409: Remove unnecessary delays")
