It's not only that -- you changed the struct name used in the code,
too.  Please describe it, too.

This change is irrelevant with your code, and should be fixed
individually.  Please drop the hunk.

So this is supposed to be Lenovo-specific, and maybe better to rename,
e.g. ALC287_FIXUP_LENOVO_TAS2781_I2C or such?

Please keep one entry per line.  Let's ignore the checkpatch
complaints.

Why this is needed at all?  IOW, which entry causes this wrong
attribute?
