Subject[PATCH 0/3] mmc: core: Avoid hogging the CPU while polling for busy
Date
Step by step, code that have been dealing sending CMD13 to poll the card for
busy, have been moved to use the common mmc_poll_for_busy() loop. This helps to
avoid hogging the CPU, for example, as it inserts a small delay in between each
polling attempt. Additionally, it avoids open coding.

This series takes the next and final step, by moving the mmc block device layer
from its own busy polling loop, into using the common code.

Please test and review!

Kind regards
Uffe
