Thanks for the report. In 6.12 struct ffa_partition_info.uuid is still
'u32 uuid[4]', not uuid_t, so uuid_copy(&buf->uuid, ...) fails to
compile. The conversion prerequisite b7c9f32614f17 ("firmware: arm_ffa:
Replace UUID buffer to standard UUID format") isn't in 6.12. Dropped the
offending patch from the 6.12 queue along with its dependency:
  - "firmware: arm_ffa: fix big-endian support in __ffa_partition_info_get_regs"

Thanks,
Sasha
