Arvind Yadav e0c24d8b27 ALSA: pcmcia: constify snd_pcm_ops structures
snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.

Stephen Barber 5a9a8eca79 ALSA: usb-audio: don't retry snd_usb_ctl_msg after timeout
A few calls to snd_usb_ctl_msg wrap the function in a retry loop. In
the worst case, the timeout for snd_usb_ctl_msg is 5 seconds, which when
retried 10 times (for example, if a device is removed) could cause a
probe to hang for ~50 seconds.

Example stack trace from 3.14 which triggered a hung task timeout:

Arvind Yadav 3066ad553d ALSA: sb16: constify snd_pcm_ops structures
snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.
