ALSA: timer: Fix leak in events via snd_timer_user_tinterrupt
commit e4ec8cc8039a7063e24204299b462bd1383184a5 upstream.
The stack object “r1” has a total size of 32 bytes. Its field
“event” and “val” both contain 4 bytes padding. These 8 bytes
padding bytes are sent to user without being initialized.
