Better to line it up like this:

		WARN_ON(mc_msi_domain->host_data !=
			&its_fsl_mc_msi_domain_info);

At 81 chars, it might be better on a single line instead.

		WARN_ON(mc_msi_domain->host_data != &its_fsl_mc_msi_domain_info);

It also might be better to shorten some of the identifiers.

Yeah.  Except you can't fight checkpatch.pl...  In the long run it will
just wear you down for no good reason.

Yeah.  Shorter names are a great idea.  This driver went a bit crazy
with all the prefixes.  It's a static variable.

What changed in v2?  That has to go below the --- line.  Please fix it
up and resend v3 with that information and read
Documentation/SubmittingPatches for all of the details about this.
