Hi Takashi,

Could you please review this patch?

[PATCH] ALSA: us122l: Add missing NULL check in
usb_stream_hwdep_mmap()

It checks for a missing stream object in usb_stream_hwdep_mmap() and
returns ENODEV instead of dereferencing NULL.

The patch is unchanged. I am copying this address for visibility.

Thanks,
