Junrui Luo 0d71b3c2ed ALSA: firewire-motu: add bounds check in put_user loop for DSP events ...

[ Upstream commit 298e753880 ]

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().
