[media] pci: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops. The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.
The semantic patch that makes this change is as follows:
