Tony Lindgren 35fba0f0fd wlcore: Use spin_trylock in wlcore_irq() to see if we need to queue tx ... We currently have a collection of flags and locking between the threaded irq and tx work: - wl->flags bitops - wl->mutex - wl->wl_lock spinlock The bitops flags do not need a spinlock around them, and we only need the spinlock to see if we need to queue tx work or not. And wlcore_irq() holds the mutex. To simplify the locking, we can use spin_trylock and always queue tx work unless we know there's nothing to do. Let's also update the comment a bit while at it.
