Hello,
I noticed (as in "my mouse stopped working") that the heuristic that
should skip USB input devices when enabling auto suspend is not working.
After staring at the code long enough I realized that there's something
wrong with:
len = readlink(filename, linkto, sizeof(link) - 1);
sizeof(link) returns the size of link(2), not the linkto char array :P
-- >8 --
readlink is failing because sizeof(link) returns the size of 'link'
which is a function, not the intended char buffer.
Fix the typo.
