Smatch warns about small size on two structs:
drivers/media/platform/qcom/venus/hfi_parser.c:103 parse_profile_level() error: memcpy() 'proflevel' too small (8 vs 128)
drivers/media/platform/qcom/venus/hfi_parser.c: drivers/media/platform/qcom/venus/hfi_parser.c:129 parse_caps() error: memcpy() 'cap' too small (16 vs 512)
The reason is that the hfi_parser actually expects:
- multiple data entries on hfi_capabilities
- multiple profile_level on hfi_profile_level_supported
However, the structs trick gcc, making it to believe that
there's just one value for each.
