The attached patch failed to apply to 5.11-stable tree, but would be preferred to be there.

commit 6d638b3ffd27036c062d32cb4efd4be172c2a65e upstream.
[Why] Current list supports modifiers that have DCC_MAX_COMPRESSED_BLOCK set to AMD_FMT_MOD_DCC_BLOCK_128B, while AMD_FMT_MOD_DCC_BLOCK_64B is used instead by userspace.
[How] Replace AMD_FMT_MOD_DCC_BLOCK_128B with AMD_FMT_MOD_DCC_BLOCK_64B for modifiers with DCC supported.
