Takashi Iwai 175b8d89fe ALSA: pcm: oss: Fix potential out-of-bounds shift ... syzbot spotted a potential out-of-bounds shift in the PCM OSS layer where it calculates the buffer size with the arbitrary shift value given via an ioctl. Add a range check for avoiding the undefined behavior. As the value can be treated by a signed integer, the max shift should be 30.
