[ndctl PATCH v3 1/8] ndctl/build: Suppress -Waddress-of-packed-member
gcc 9.1.1 emits a slew of warnings for many of the command field
accesses. I.e. warnings of the form:
libndctl.c:2586:21: warning: taking address of packed member of ‘struct
nd_cmd_get_config_data_hdr’ may result in an unaligned pointer value
[-Waddress-of-packed-member]
2586 | cmd->iter.offset = &cmd->get_data->in_offset;
| ^~~~~~~~~~~~~~~~~~~~~~~~~
Suppress these as fixing the warning would defeat the abstraction of being able
to have common code that operates on commands with common fields at different
offsets in the payload.
