Revert structure cs35l41_dev_name and redefine tas2781_generic_fixup.

Signed-off-by: Shenghao Ding shenghao-ding@ti.com

Now the patches are better split. But, a few fundamental things are still missing:

- Please describe the reason why this is needed; it's often more important than describing the change itself.

- Give more proper subject for each patch; "Update tas2781 HDA driver" tells nothing really what and why.

thanks,

Takashi

Changes in v1:

• Redefine tas2781_generic_fixup, remove hid param
• revert from scodec_dev_name back to cs35l41_dev_name, it is unnecessary for tas2781
