Re: [staging/FmpDevicePkg-master][PATCH 2/2] FmpDevicePkg FmpDxe: Use Attributes to know whether reset is required

["Zeng, Star" <star.zeng@intel.com>]

Oh, you are right. The flag mDescriptorPopulated means populated or not, but not populating needed or not.

Will send new patch soon.

Thanks,
Star

Star,

I think the logic may be reversed.

The original logic tested !Pcd value.

The new logic checks if the attribute and setting are != 0.

I think it should check if the attribute and setting are 0.
