Hi, Incorrect mask of Soundwire ports - one bit too long/big - was passed. Theoretically, too wide mask could cause an out of bounds read in sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy driver, e.g. adding incorrect number of ports via sdw_stream_add_slave(). Not adding Cc-stable because I don't think the issue can lead to real out-of-bounds read.
