-Subject: [PATCH] soundwire: intel: Initialize clock stop timeout
-
-The bus->clk_stop_timeout member is only initialized to a non-zero value
-during the codec driver probe. This can lead to corner cases where this
-value remains pegged at zero when the bus suspends, which results in an
-endless loop in sdw_bus_wait_for_clk_prep_deprep().
-
-Corner cases include configurations with no codecs described in the
-firmware, or delays in probing codec drivers.
-
-Initializing the default timeout to the smallest non-zero value avoid this
-problem and allows for the existing logic to be preserved: the
-bus->clk_stop_timeout is set as the maximum required by all codecs
-connected on the bus.
