[PATCH AUTOSEL 4.19 324/671] ASoC: fix valid stream condition

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jerome Brunet <jbrunet@xxxxxxxxxxxx>

[ Upstream commit 6a7c59c6d9f3b280e81d7a04bbe4e55e90152dce ]

A stream may specify a rate range using 'rate_min' and 'rate_max', so a
stream may be valid and not specify any rates. However, as stream cannot
be valid and not have any channel. Let's use this condition instead to
determine if a stream is valid or not.

Fixes: cde79035c6cf ("ASoC: Handle multiple codecs with split playback / capture")
