we need to run a platform dependant function changing GPIOs which need a
specific time between those changes. Actually it is the platform set_power
function used by platform_lcd_probe. This itself is no problem. But the
currently used msleeps on about 250ms summarized is really much while the
We'd like to avoid idle during that msleeps. So, we used a work_queue in that
set_power function. But unforturnatly do_initcalls calls flush_scheduled_work
at the end. So the system will still idle until this work_queue has finished.
What can we use to call the set_power function asynchronously and sleepable
while not waiting during system startup on this function to be finished? The
set_power just enabled the lcd power and nothing need to wait on that.
