[PATCH] bus: mhi: clean up some kernel-doc warnings

From: Randy Dunlap

Date: Sun Jul 19 2026 - 18:32:43 EST


Clean up some kernel-doc comments and warnings:
- use correct format for struct members
- add one struct member description
- add one function parameter description
- mark one enum as private
- add a leading '*' on one kernel-doc line

Fixes these warnings:
Warning: include/linux/mhi.h:108 struct member 'target_link_speed' not
described in 'mhi_link_info'
Warning: include/linux/mhi.h:108 struct member 'target_link_width' not
described in 'mhi_link_info'
Warning: ../include/linux/mhi.h:159 Enum value 'MHI_STATE_MAX' not
described in enum 'mhi_state'
Warning: ../include/linux/mhi.h:212 bad line: for UL channels, multiple
of 8 ring elements for DL channels
Warning: ../include/linux/mhi.h:236 struct member 'wake_capable' not
described in 'mhi_channel_config'
Warning: ../include/linux/mhi.h:449 struct member 'M0' not described
in 'mhi_controller'
Warning: ../include/linux/mhi.h:449 struct member 'M2' not described
in 'mhi_controller'
Warning: ../include/linux/mhi.h:449 struct member 'M3' not described
in 'mhi_controller'
Warning: ../include/linux/mhi.h:528 struct member 'id_table' not described
in 'mhi_driver'
Warning: ../include/linux/mhi.h:543 function parameter 'mhi_cntrl' not
described in 'mhi_free_controller'
