[PATCH] drm/display/dp: fix all kernel-doc warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix a struct member name in &struct drm_dp_as_sdp.
Add Returns: kernel-doc syntax for 4 functions.
In the Returns: sections, spell "%true" and "%false" consistently.

Fixes these kernel-doc warnings:

drm_dp_helper.h:126: warning: Function parameter or struct member 'mode' not described in 'drm_dp_as_sdp'
drm_dp_helper.h:126: warning: Excess struct member 'operation_mode' description in 'drm_dp_as_sdp'
drm_dp_helper.h:237: warning: No description found for return value of 'drm_dp_dsc_sink_supports_format'
drm_dp_helper.h:539: warning: No description found for return value of 'drm_dp_dpcd_readb'
drm_dp_helper.h:554: warning: No description found for return value of 'drm_dp_dpcd_writeb'
drm_dp_helper.h:721: warning: No description found for return value of 'drm_dp_has_quirk'
