Hi Maciek,

Please test your solution thoroughly before submitting
the next version. Writing to debugfs register attribute
fails due to lack of proper copying from user memory,
which makes testing impossible.

Hi, thanks for the comment. Indeed, I noticed the problem just after
sending the patch. Surprisingly this didn't fail on iMX6 for some
reason.

Aside from the __user access problem, is the approach, in general, ok for
you or would you suggest that I changed something?

At first glance the feature looks nice. I'll be able to say more
after testing working version.
