Pull irq cleanups from Thomas Gleixner:
 "A series of treewide cleanups to ensure interrupt request consistency.

   - Add the missing IRQF_COND_ONESHOT flag to devm_request_irq()

     This is inconsistent vs request_irq() and causes the same issues
     which where addressed with the introduction of this flag

   - Cleanup IRQF_ONESHOT and IRQF_NO_THREAD usage

     Quite some drivers have inconsistent interrupt request flags
     related to interrupt threading namely IRQF_ONESHOT and
     IRQF_NO_THREAD. This leads to warnings and/or malfunction when
     forced interrupt threading is enabled.

   - Remove stub primary (hard interrupt) handlers

     A bunch of drivers implement a stub primary (hard interrupt)
     handler which just returns IRQ_WAKE_THREAD. The same functionality
     is provided by the core code when the primary handler argument of
     request_thread_irq() is set to NULL"
