The combination of "local_save_flags" and "local_irq_disable" seems to be
equivalent to "local_irq_save" (see code snips below). Consequently, replace
occurrences of local_save_flags+local_irq_disable with local_irq_save.

* local_irq_save
#define raw_local_irq_save(flags) \
                do { (flags) = __raw_local_irq_save(); } while (0)

static inline unsigned long __raw_local_irq_save(void)
{
        unsigned long flags = __raw_local_save_flags();

        raw_local_irq_disable();

        return flags;
}

* local_save_flags
#define raw_local_save_flags(flags) \
                do { (flags) = __raw_local_save_flags(); } while (0)
