People are blamed for doing more-then-one-thing-per-patch,
so I prefer send only one big patch fixing all spelling errors and
coding style on further work.

yes, I take care of this:--- a/drivers/staging/crystalhd/crystalhd_misc.h

You are right, this code really have some unnecessary messages,
perhaps it could be done on further patch, all at once.
The main idea on this patch is just replace convert the old macro to pr_err.

yes, it could be done together with the coding style issues.

there is a lot of work to do on this driver.

Many thanks for your comments.
