Revert "video: hgafb: fix potential NULL pointer dereference"
This reverts commit ec7f6aad57ad29e4e66cc2e18e1e1599ddb02542. Because of recent interactions with developers from, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. This patch "looks" correct, but the driver keeps on running and will fail horribly right afterward if this error condition ever trips. So points for trying to resolve an issue, but a huge NEGATIVE value for providing a "fake" fix for the problem as nothing actually got resolved at all. I'll go fix this up properly...
