      ALSA: hda - Fix inconsistent pin states after resume · 31614bb8
      Takashi Iwai 提交于
      The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a
      module parameter] introduced the polling jack detection code, but it
      also moved the call of snd_hda_jack_set_dirty_all() in the resume path
      after resume/init ops call.  This caused a regression when the jack
      state has been changed during power-down (e.g. in the power save
      mode).  Since the driver doesn't probe the new jack state but keeps
      using the cached value due to no dirty flag, the pin state remains
      also as if the jack is still plugged.
      
      The fix is simply moving snd_hda_jack_set_dirty_all() to the original
      position.

      Revert "drivers/misc/ti-st: remove gpio handling" · a7e2ca17
      Luciano Coelho 提交于
      This reverts commit eccf2979.
      
      The reason is that it broke TI WiLink shared transport on Panda.
      Also, callback functions should not be added to board files anymore,
      so revert to implementing the power functions in the driver itself.
      
      Additionally, changed a variable name ('status' to 'err') so that this
      revert compiles properly.

      async: fix __lowest_in_progress() · f56c3196
      Tejun Heo 提交于
      Commit 083b804c ("async: use workqueue for worker pool") made it
      possible that async jobs are moved from pending to running out-of-order.
      While pending async jobs will be queued and dispatched for execution in
      the same order, nothing guarantees they'll enter "1) move self to the
      running queue" of async_run_entry_fn() in the same order.
      
      Before the conversion, async implemented its own worker pool.  An async
      worker, upon being woken up, fetches the first item from the pending
      list, which kept the executing lists sorted.  The conversion to
      workqueue was done by adding work_struct to each async_entry and async
      just schedules the work item.  The queueing and dispatching of such work
      items are still in order but now each worker thread is associated with a
      specific async_entry and moves that specific async_entry to the
      executing list.  So, depending on which worker reaches that point
      earlier, which is non-deterministic, we may end up moving an async_entry
      with larger cookie before one with smaller one.
      
      This broke __lowest_in_progress().  running->domain may not be properly
      sorted and is not guaranteed to contain lower cookies than pending list
      when not empty.  Fix it by ensuring sort-inserting to the running list
      and always looking at both pending and running when trying to determine
      the lowest cookie.
      
      Over time, the async synchronization implementation became quite messy.
      We better restructure it such that each async_entry is linked to two
      lists - one global and one per domain - and not move it when execution
      starts.  There's no reason to distinguish pending and running.  They
      behave the same for synchronization purposes.
