drivers/isdn/hardware/mISDN: Use GFP_ATOMIC when a lock is held
The function inittiger is only called from nj_init_card, where a lock is held.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@gfp exists@
identifier fn;
position p;
@@
fn(...) {
... when != spin_unlock_irqrestore
when any
GFP_KERNEL@p
... when any
}
@locked@
identifier gfp.fn;
@@
spin_lock_irqsave(...)
... when != spin_unlock_irqrestore
fn(...)
@depends on locked@
position gfp.p;
@@
- GFP_KERNEL@p
+ GFP_ATOMIC
// </smpl>
