scripts: kernel-doc: fix macro handling in enums
drivers/net/ethernet/intel/idpf/idpf.h uses offsetof to initialize the enum enumerators: enum idpf_cap_field { IDPF_BASE_CAPS = -1, IDPF_CSUM_CAPS = offsetof(struct virtchnl2_get_capabilities, csum_caps), IDPF_SEG_CAPS = offsetof(struct virtchnl2_get_capabilities, seg_caps), IDPF_RSS_CAPS = offsetof(struct virtchnl2_get_capabilities, rss_caps), IDPF_HSPLIT_CAPS = offsetof(struct virtchnl2_get_capabilities, hsplit_caps), IDPF_RSC_CAPS = offsetof(struct virtchnl2_get_capabilities, rsc_caps), IDPF_OTHER_CAPS = offsetof(struct virtchnl2_get_capabilities, other_caps), }; kernel-doc parses the above enumerator with a ',' inside the macro and treats 'csum_caps', 'seg_caps' etc. also as enumerators resulting in the warnings: drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'csum_caps' not described in enum 'idpf_cap_field' drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'seg_caps' not described in enum 'idpf_cap_field' drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'rss_caps' not described in enum 'idpf_cap_field' drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'hsplit_caps' not described in enum 'idpf_cap_field' drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'rsc_caps' not described in enum 'idpf_cap_field' drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value 'other_caps' not described in enum 'idpf_cap_field' Fix it by removing the macro arguments within the parentheses.
