When a caller passes NULL, uuid_parse() ->\n__uuid_parse() -> uuid_is_valid() dereferences the pointer, causing\na kernel panic:\n\n  |  Unable to handle kernel NULL pointer dereference at virtual address\n  |  0000000000000040\n  |  pc : uuid_parse+0x40/0xac\n  |  lr : ffa_partition_info_get+0x1c/0x94 [arm_ffa]\n\nAdd a NULL guard before uuid_parse() so a NULL argument returns\n-ENODEV instead of crashing.
