The generic description goes above the "---" line, the incremental
history of the patch usually below.

What is there seems ok, but it is not enough yet. The quirks can also go
from the users.
After that, it gets even more complicated; after this patch
'host->timeout_clk' becomes obsolete which should probably cleaned up in
a later patch together with host->ops->get_timeout_clk. Hmmmm, that
needs careful auditing.
