Hi Chris,

I was wondering if you were going to apply this to the mmc tree.  Since
the module_param addition isn't in the module.h baseline, I'd be
speculatively fixing an issue that hasn't been created yet, which isn't
the end of the world, but it doesn't feel quite right to do that either.

If it is in the mmc tree, then the include fix will be guaranteed to be
present wherever the module_param usage is present.

Thanks,
Paul.

Subject: [PATCH] mmc: using module_param requires the inclusion of
 moduleparam.h

Commit "mmc: add module param to set fault injection attributes" adds
a module_param to this file.  But it is relying on the old implicit
"module.h is everywhere" behaviour, and without the explicit include
of moduleparam.h, the pending module.h split up produces this error:

drivers/mmc/core/debugfs.c:28:35: error: expected ')' before numeric constant
