From: Dan Bogdan Nechita <dan.bogdan.nechita@gmail.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 1bb850a1b7f68b66361e658e334f9fdf8231f17d upstream.
Currently writing the attributes with "echo" will result in comparing: "enabled\n" with "enabled\0" and attribute is always set to false.
Use the sysfs_streq() instead because it treats both NUL and new-line-then-NUL as equivalent string terminations.
