Charles Keepax ccb7bb13c0 soundwire: Move handle_nested_irq outside of sdw_dev_lock ... The sdw_dev_lock protects the SoundWire driver callbacks against the probed flag, which is used to skip the callbacks if the driver gets removed. For more information see commit bd29c00edd ("soundwire: revisit driver bind/unbind and callbacks"). However, this lock is a frequent source of mutex inversions. Many audio operations eventually hit the hardware resulting in a SoundWire callback, this means that typically the driver has the locking order ALSA/ASoC locks -> sdw_dev_lock. Conversely, the IRQ comes in directly from the SoundWire hardware, but then will often want to access ALSA/ASoC, such as updating something in DAPM or an ALSA control. This gives the other lock order sdw_dev_lock -> ALSA/ASoC locks. When the IRQ handling was initially added to SoundWire this was through a callback mechanism. As such it required being covered by the lock because the callbacks are part of the sdw_driver structure and are thus present regardless of if the driver is currently probed. Since then a newer mechanism using the IRQ framework has been added, which is currently covered by the same lock but this isn't actually required. Handlers for the IRQ framework are registered in probe and should by released during remove, thus the IRQ framework will have already unbound the IRQ before the slave driver is removed. Avoid the aforementioned mutex inversion by moving the handle_nested_irq call outside of the sdw_dev_lock.
