mmc: core: Fix error propagation for some ioctl commands
[ Upstream commit f19c5a73 ] Userspace has currently no way of checking the internal R1 response error bits for some commands. This is a problem for some commands, like RPMB for example. Typically, we may detect that the busy completion has successfully ended, while in fact the card did not complete the requested operation. To fix the problem, let's always poll with CMD13 for these commands and during the polling, let's also aggregate the R1 response bits. Before completing the ioctl request, let's propagate the R1 response bits too. Reviewed-by:Avri Altman <avri.altman@wdc.com> Co-developed-by:
