Subject: Use sema_init() instead of init_MUTEX()
X-Git-Url: http://git.ozo.com/?a=commitdiff_plain;h=df2b041849c0c6bcadd22458006cb283de38a386;p=madwifi%2F.git

Use sema_init() instead of init_MUTEX()

init_MUTEX() is missing on kernels with realtime patches.  Besides,
init_MUTEX is a confusing name, since it initializes a semaphore,
whereas newer kernels have real mutexes as well.
