Re: [PATCH v2] fbdev: platinumfb: add error checking for ioremap calls

The ioremap() and ioremap_wt() calls in platinumfb_probe() were not
checked for failure. If any of these mappings fail, the driver would
dereference NULL pointers, leading to a kernel panic.

Add proper error checking and use goto-based cleanup to avoid code
duplication across the error paths.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

That Fixes line ^^^ has no value, so I dropped it.

Would be nice to have your Name written out here, e.g. Yue Bing Kun (or something),
but I've left it as-is for now. In case you resend with full name, I can replace it
in the git tree.

Patch applied (with the Fixes line dropped).
