Instead of
static struct list_head foo;
static struct mutex bar;
...
INIT_LIST_HEAD(&foo);
mutex_init(&bar);
just do
static LIST_HEAD(foo);
static DEFINE_MUTEX(bar);
Also remove some superfluous struct list_head and spinlock_t
initialization calls where the variables are already defined using
macros that initialize them.
This saves a decent amount of compiled code too:
