      driver-core: remove sysdev.h usage. · edbaa603
      Kay Sievers authored
      The sysdev.h file should not be needed by any in-kernel code, so remove
      the .h file from these random files that seem to still want to include
      it.
      
      The sysdev code will be going away soon, so this include needs to be
      removed no matter what.

      freezer: implement and use kthread_freezable_should_stop() · 8a32c441
      Tejun Heo authored
      Writeback and thinkpad_acpi have been using thaw_process() to prevent
      deadlock between the freezer and kthread_stop(); unfortunately, this
      is inherently racy - nothing prevents freezing from happening between
      thaw_process() and kthread_stop().
      
      This patch implements kthread_freezable_should_stop() which enters
      refrigerator if necessary but is guaranteed to return if
      kthread_stop() is invoked.  Both thaw_process() users are converted to
      use the new function.
      
      Note that this deadlock condition exists for many of freezable
      kthreads.  They need to be converted to use the new should_stop or
      freezable workqueue.
      
      Tested with synthetic test case.

      >From my POV, it looks like the hardware is not working as expected
      and returns a bogus data rate. The driver doesn't check the result
      and directly uses it as some sort of divisor in some places:
      
      msleep(lis3->pwron_delay / lis3lv02d_get_odr());
      
      Under this circumstances, this could very well cause the
      "divide by zero" exception from above.
      
      For now, I fixed it the easiest and most obvious way:
      Check if the result is sane and if it isn't use a sane default
      instead. I went for "100" in the latter case, simply because
      /sys/devices/platform/lis3lv02d/rate returns it on a successful
      boot.
