Adrian Knoth f7de8ba3fc ALSA: hdspm - Provide unique driver id based on card serial
Before, /proc/asound looked like this:

 2 [Default        ]: HDSPM - RME RayDAT_f1cd85
                      RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18

In case of a second HDSPM card, its name would be Default_1. This is
cumbersome, because the order of the cards isn't stable across reboots.

To help userspace tools referring to the correct card, this commit
provides a unique id for each card:

 2 [HDSPMxf1cd85   ]: HDSPM - RME RayDAT_f1cd85
                      RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18

In this example, userspace (configuration files) would then use
hw:HDSPMxf1cd85 to choose the right card.

The serial is masked to 24bits, so this string is always shorter than
sixteen chars.

Takashi Iwai 80c8a2a372 ALSA: usb-audio - Avoid flood of frame-active debug messages
With some buggy devices, the usb-audio driver may give "frame xxx active"
kernel messages too often.  Better to keep it as debug-only using
snd_printdd(), and also add the rate-limit for avoiding floods.

Xi Wang 4fa0e81b83 ALSA: usb-audio: fix possible hang and overflow in parse_uac2_sample_rate_range()
A malicious USB device may feed in carefully crafted min/max/res values,
so that the inner loop in parse_uac2_sample_rate_range() could run for
a long time or even never terminate, e.g., given max = INT_MAX.

Also nr_rates could be a large integer, which causes an integer overflow
in the subsequent call to kmalloc() in parse_audio_format_rates_v2().
Thus, kmalloc() would allocate a smaller buffer than expected, leading
to a memory corruption.

To exploit the two vulnerabilities, an attacker needs physical access
to the machine to plug in a malicious USB device.

This patch makes two changes.

1) The type of "rate" is changed to unsigned int, so that the loop could
   stop once "rate" is larger than INT_MAX.

2) Limit nr_rates to 1024.
