ALSA: firewire-motu: add bounds check in put_user loop for DSP events
[ Upstream commit 298e753880b6ea99ac30df34959a7a03b0878eed ]
In the DSP event handling code, a put_user() loop copies event data.
When the user buffer size is not aligned to 4 bytes, it could overwrite
beyond the buffer boundary.
Fix by adding a bounds check before put_user().
