[PATCH 7/7] staging: wilc1000: Remove unused inclusion of semaphore header

From: Binoy Jayan
Date: Mon Jun 13 2016 - 06:38:46 EST


Remove unused inclusions of semaphore header and remove the same
from the todo list. Also remove the now unused wrapper 'wilc_lock_timeout'.
Semaphores are going away in the future.
