Please do not do that. There are valid kernel apis to grant access to<br>
registers easily, and creating random files and directories in the root<br>
of sysfs is not only the incorrect way of doing it, you are making more<br>
work for yourself to do so, adding more code that is not needed.<br>
<br>
Do you have a pointer to the code so that we can provide help with<br>
showing the "correct" way to do all of this?<br>
<br>
thanks,<br>
