Subject[PATCH 1/2] ASoC: wcd9335: fix order of Slimbus unprepare/disable
Date
Slimbus streams are first prepared and then enabled, so the cleanup path
should reverse it. The unprepare sets stream->num_ports to 0 and frees
the stream->ports. Calling disable after unprepare was not really
effective (channels was not deactivated) and could lead to further
issues due to making transfers on unprepared stream.
