Subject: [PATCH] proper flags type of spin_lock_irqsave()
Signed-off-by: Alexey Dobriyan <adobriyan@...il.com>
---
So far results of incomplete spin_lock_irqsave audit, and there is also
local_irq_save()... I'll eventually add
typedef unsigned long __bitwise__ lock_flags_t;
so sparse could find future offenders. name OK?
