It combines the cleanup I've been working on and the addition of the new API call request_firmware_cache() for fixing a corner case suspend issue on some type of cards with an optimization in place where the firmware is *not* needed on reboot. The cleanup work allows us to test the firmware API with one kernel configuration. I've addressed Kees' feedback on this respin and combined the code into drivers/base/firmware_class/. I've made one new test_firmware change in consideration for one firmware change, the patch "firmware: ensure the firmware cache is not used on incompatible calls" requires us to modify our tests scripts to use the APIs sanely as well. I've put up these changes on my git tree, refer to the branch "20180307-firmware-dev-for-v4.17" based on linux-next [0] and the same name based on Linus' tree [1]. Questions, feedback, and specially rants are always welcomed.
