|
When calling debugfs functions, there is no need to ever check the
|
|
return value. The function can work or not, but the code logic should
|
|
never do something different based on this.
|
|
|
|
This cleans up a lot of unneeded code and logic around the debugfs
|
|
files, making all of this much simpler and easier to understand.
