So, is it boolean or integer? This code makes it confusing a lot.
It is a boolean, so now I've updated with this:
if (ctrl_reg & M41TXX_BIT_FT)
return scnprintf(buf, PAGE_SIZE, "on\n");
else
return scnprintf(buf, PAGE_SIZE, "off\n");
No, it has to be consistent with what you write.
Here, you'd write 0 or 1 in the file and read off or on...
I'm submitting too many patches, without waiting, sorry.
I've submitted v6 patchset(too early), can you please take a look there
and tell if I'm on the right path? On that I've change also _store
function with kstrtobool().
I'm sorry I'm doing so much confusion.
I'm trying to learn to make it the best way.
