Baisong Zhong cf59e1e4c7 ALSA: seq: fix undefined behavior in bit shift for SNDRV_SEQ_FILTER_USE_EVENT ... Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in sound/core/seq/seq_clientmgr.c:509:22 left shift of 1 by 31 places cannot be represented in type 'int' ...
