From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx> Hi, While reviewing all the complete_all() users, I realized there is recouring pattern how the completion API is used to synchronize the stages of the firmware loading. Since firmware_class.c contains a fairly complete implemetation for synching the loading, it worthwhile to export it and reuse it in drivers, At the same time one complete_all() user is gone which is a good thing for -rt (*). The first 2 patches are bug fixes for the test script. Patch 3 adds the new API, and the following patches update a few drivers. I haven't updated all the drivers because I wanted to see first if this is going into the right direction. Since naming is a difficult, I am more than please to pick a better name if you have one. cheers, daniel (*) Under -rt waking all waiters via complete_all() is not good. If the complete_all() call happens in IRQ context we have an unbound latency there. Therefore the aim is to reduce the complete_all() users and get rid of them where possible.
