There exists several separate variants of polling loops, used to detect when the card stop signals busy for various operations, in the mmc core. All of them have different issues that needs to be fixed. The intent with this series, is to address some of these problems, via first improving the mmc_poll_for_busy() function, then consolidate code by moving more users to it. While I was working on this, I stumbled over some code here and there, that deserved some cleanup, hence I also folded in a couple of patches for this. So far, I have only managed to extensively test the updated mmc_poll_for_busy() function for CMD6 commands. Some tests for erase/trim/discard and for HPI+sanitize are needed. Note that, there are still separate polling loops in the mmc block layer, but moving that to mmc_poll_for_busy() involves some additional work. I am looking into that as a next step. Please help review and test!
