I am not convinced that this is needed because exynos4212-jpeg is equal
to exynos4210-jpeg... It is a little bit weird because Jacek's commit
3246fdaa0ac2d9 ("[media] s5p-jpeg: Add support for Exynos3250 SoC")
changed the driver data for Exynos4210 from S5P to Exynos4 without
explaining it... However if these compatibles are exactly equal then
only one should be preferred. It makes everything easier. Second can be
still documented e.g. as deprecated.

Best regards,
Krzysztof
