Shall I still wait? I would apply it to give the testing in -next. I got the information that the crash was not reproduced, thus probably not related to this patch.

Commits 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the values correct for Exynos5422 Odroids") and 9ff416cf45a0 ("ARM: dts: exynos: Disable frequency scaling for FSYS bus on Odroid XU3 family") revealed that 'opp-shared' property for the Exynos bus OPPs was used incorrectly, what had the side-effect of disabling frequency scaling for the second and latter buses sharing given OPP-table. Fix this by removing bogus 'opp-shared' properties from Exynos3 bus OPP-tables. This restores frequency scaling for the following busses: RightBus, LCD0, FSYS and MFC.
