i2c: __must_check fixes (core drivers)
Check for error on sysfs file creation.
Check for error on device registration.
Check for error on class device registration.
Greg, I am not familiar with completion, can you please tell me if I
need to take care of it in the error paths (as I did in this patch,
see /* Needed? */ comments), or if it isn't needed?
These patches were tested, including forced errors, so they should work
fine. But of course more testing can't hurt.
