[PATCH] drm: Fix no_vblank field references in documentation

From: Marijn Suijten
Date: Tue Apr 16 2024 - 16:08:42 EST


Browsing the DRM documentation shows that drm_crtc_state.no_vblank
is not turned into a reference to the no_vblank field, but rather a
reference to `struct drm_crtc_state`. The only difference with other
field references is that the struct name is prefixed by the literal
`struct` tag, despite also already having a `&` reference prefix in two
of the three cases. Remove the `struct` prefix to turn these references
into proper links to the designated field.

Fixes: 7beb691f1e6f ("drm: Initialize struct drm_crtc_state.no_vblank from device settings")

Note that a simple regex like "&struct \w+\.\w+" shows that there are
only a handful of violators, most of them inside DRM files. Let me know
if you'd like a v2 that addresses all of them in one go (in separate
patches or one combined change)?

Kind regards,
Marijn
