+Subject: soundwire: intel: Initialize clock stop timeout
+
+From: Sjoerd Simons <sjoerd@collabora.com>
+
+commit 13c30a755847c7e804e1bf755e66e3ff7b7f9367 upstream.
+
+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.
+
+Fixes: 1f2dcf3a154ac ("soundwire: intel: set dev_num_ida_min")
