Mike,

Sorry I missed your earlier comment about this. My bad.

Now, about my reply to Sergei:
      * Sergei identified the problem, and proposed a valid fix. It's
        only fair he gets credited for his work (yes, you did it before
        he did, but I didn't know it). The SOB on a patch is the proper
        way of managing the attribution.
      * Posting a patch is the quickest way for the maintainer (in this
        case David) to be able to push a fix to mainline.
      * It also helps other folks reading the ML and facing the same
        issue. They can grab the patch, apply it locally and go on with
        their own stuff until the patch is merged.
      * The person reporting the problem probably has a configuration
        showing the problem. If any of my platforms had shown that
        error, I would have fixed it long before it hit the mailing
        list.

Now, to keep everyone happy, an untested patch. David, can you please
apply it?

Cheers,

	M.

Subject: [PATCH] MTD: Fix physmap compilation error

Commit b7281ca2a4 (MTD: Add integrator-flash feature to physmap)
broke some platforms by using 'struct platform_device' without
declaring it.

Add a forward declaration to keep everyone happy.

Fix proposed by both Mike Frysinger and Sergei Shtylyov.
