docs-rst: kernel-doc: fix typedef output in RST format
When using a typedef function like this one: typedef bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle); The Sphinx C domain expects it to create a c:type: reference, as that's the way it creates the type references when parsing a c:function:: declaration. So, a declaration like: .. c:function:: bool v4l2_valid_dv_timings (const struct v4l2_dv_timings * t, const struct v4l2_dv_timings_cap * cap, v4l2_check_dv_timings_fnc fnc, void * fnc_handle) Will create a cross reference for :c:type:`v4l2_check_dv_timings_fnc`. So, when outputting such typedefs in RST format, we need to handle this special case, as otherwise it will produce those warnings: ./include/media/v4l2-dv-timings.h:43: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc ./include/media/v4l2-dv-timings.h:60: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc ./include/media/v4l2-dv-timings.h:81: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc So, change the kernel-doc script to produce a RST output for the above typedef as: .. c:type:: v4l2_check_dv_timings_fnc **Typedef**: timings check callback **Syntax** ``bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle);`` Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
