2013-03-17iio: events: Make iio_push_event() IRQ context saveLars-Peter Clausen
Currently it is not save to call iio_push_event() from hard IRQ context since the IIO event code uses spin_lock()/spin_unlock() and it is not save to mix calls to spin_lock()/spin_unlock() from different contexts on the same lock. E.g. if the lock is being held in iio_event_chrdev_read() and an interrupts kicks in and the interrupt handler calls iio_push_event() we end uo with a deadlock. This patch updates iio_push_event() to use spin_lock_irqsave()/ spin_unlock_irqstrestore(), since it can be called from both IRQ and non-IRQ context. All other other users of the lock, which are always run in non-IRQ context, are updated to spin_lock_irq()/spin_unlock_irq().
