[AMD Public Use]
+ if (adev->ras_features & AMDGPU_RAS_BLOCK__UMC)
ras_feature is in bitmask, so it should be 1 << block or use BIT macro here for the check

Subject: [PATCH] drm/amdgpu: drop duplicated ecc check for vega10 (v2)
The same ECC check has been executed in amdgpu_ras_init for vega10, prior to gmc_v9_0_late_init.
v2: drop all atombios helper callings
