To properly manage commands awaiting R1B responses, the capability
MMC_CAP_NEED_RSP_BUSY is enabled in mmci driver, for variants that
manage busy detection.
This R1B management needs both the flags MMC_CAP_NEED_RSP_BUSY and
MMC_CAP_WAIT_WHILE_BUSY to be enabled together.

Shouldn't this have Fixes: tag ?

Hi Marek,

There is no unique patch that brought the issue, but a combination of several things:
- The series that brought the MMC_CAP_NEED_RSP_BUSY flag [1]
- The series that enabled MMC_ERASE for all hosts [2] (removal of MMC_CAP_ERASE)

But you're right, this patch may go on v5.8.x kernel and newer versions.

I think there will be quite some interest in 5.10.y LTS on the MP1 from the various industrial/embedded users, so it would be nice to have that 5.10.y well maintained with necessary backports / fixes :)
