Subject: [PATCH] exynos-gsc: Clean up file handle in open() error path.

The File handle is not yet added in the vfd list.So no need to call
v4l2_fh_del(&ctx->fh) if it fails to create control.

I think I see this and exynos4-is patch for the third time...
1. sent in a very short time-frame (usually resending is after 2 weeks),
2. without any change log (should be after --- separator),
3. with different subjects (really...),
4. without versioning (use git format-patch -v2 etc).

Please, keep it a little bit more organized... Look at examples on
mailing lists how (and when) people are sending patches.

Best regards,
Krzysztof
