From 5f928b956760bc34ff314e9c8962066c230a05b9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 1 Jun 2015 21:06:38 +0200 Subject: [PATCH] staging: wilc1000: simplify semaphore wrapper The driver has its own API for semaphores. This should be replaced with mutexes and completions, but for the moment we can start by removing the obviously unused parts.
