Huh? This commit log message also is unrelated to the patch below,
please separate and submit two separate patches.

Actually I'd like to apply this patch to linux-next-pending/ not to
crap/ as you *did* post the patch upstream right? It just is not
getting applied yet for the reasons you stated.

This not accurate, you did publish the patch, this goes into
linux-next-pending and you instead need a "Reason for not being merged
yet" or for adding it to the linux-next-pending/ directory.

You should still ask the maintainer for an alternative, otherwise the
device unusable. Did you submit the patch first in [PATCH] form? If
not please submit the patch, all I saw as an RFC and no followup at
all.
