ALSA: hda/cs8409: Increase delay during jack detection
Browse files Browse the repository at this point in the history
[ Upstream commit 8cd0765 ]

Commit c8b4f08 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.
