Hi Bhumika,

[auto build test ERROR on sound/for-next]
[also build test ERROR on v4.10-rc5 next-20170125]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

Note: the linux-review/Bhumika-Goyal/sound-pci-cs46xx-constify-snd_pcm_ops-structures/20170126-230341 HEAD 59da8ce3cc92652020c8c6a3ad0a4b11d8ee5a48 builds fine.
It only hurts bisectibility.

All errors (new ones prefixed by >>):
