[PATCH 0/3] ALSA: usb-audio: fix OOB and return value check

[Jaejoong Kim <climbbb.kim@gmail.com>]

Hi,

This patch series fixes the out-of-bound error caused by the return value
of usb_string(). It was descovered by KASAN. The Patch 1 is the V2 about
http://www.spinics.net/lists/alsa-devel/msg69487.html

Chanes in V2:
 - put an explicit error bail out(by Takashi iwai)

Patch1 was founded by connecting the following product.
http://www.lg.com/uk/lg-friends/lg-AFD-1200

I found that it only check if the return value from usb_string() is always
zero while modifying OOB KASAN message. So instead of making the
modifications to OOB to V2, I sent a patch series.

I am sorry to break the mail thread.

Thanks
