OMAP: DSS2: Replace strncmp() with sysfs_streq() in overlay_manager_store()
The function overlay_manager_store currently fails if the sysfs input is a prefix string of an existing overlay manager name. This occurs because strncmp compares the two strings only till the length of the input sysfs string. So a sysfs input "lcd" will match manager name "lcd2" which is incorrect behavior. The use of sysfs_streq here will prevent this false positive match to occur. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
