commit f00ab14c252ac459e86194747a1f580ab503c954 upstream.
This used to return -EFAULT, but the function above returns -EINVAL on
the same condition so let's stick to that.
The removal of error return on this path was introduced with b093410c9aef
('mmc: block: copy resp[] data on err for MMC_IOC_MULTI_CMD').
Fixes: b093410c9aef ('mmc: block: copy resp[] data on err for
MMC_IOC_MULTI_CMD').
