In a few places in sequencer core, we temporarily unlock / re-lock the pool spin lock while waiting for the allocation in the blocking mode. There spin_unlock_irq() / spin_lock_irq() pairs are called while initially spin_lock_irqsave() is used (and spin_lock_irqrestore() at the end of the function again). This is likely OK for now, but it's a bit confusing and error-prone. This patch replaces these temporary relocking lines with the irqsave variant to make the lock/unlock sequence more consistently.
