5d4af1be06 ALSA: us122l: add snd_us122l_free()
Use it to clean up snd_us122l_card_used[].

Without patch unplugging of an US122L soundcard didn't reset the
corresponding element of snd_us122l_card_used[] to 0.
The (SNDRV_CARDS + 1)th plugging in did not result in creating the soundcard
device anymore.
Index values supplied with the modprobe command line were not used correctly
anymore after the first unplugging of an US122L.

f4e9749f45 ALSA: Use usb_set/get_intfdata
Use the USB functions usb_get_intfdata and usb_set_intfdata instead of
dev_get_drvdata and dev_set_drvdata, respectively.

The semantic patch that makes this change for the usb_get_intfdata case is
as follows: (http://www.emn.fr/x-info/coccinelle/)
