That sounds like a reference to a DRM driver structure to me. What about attached_dev or consumer_dev or encoder_dev?

Thanks for doing this - it helps readability. checkpatch complained: -:107: CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis #107: FILE: drivers/gpu/drm/bridge/nxp-ptn3460.c:251: + ret = drm_connector_init(bridge->drm, &ptn_bridge->connector, &ptn3460_connector_funcs, DRM_MODE_CONNECTOR_LVDS); -:133: CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis #133: FILE: drivers/gpu/drm/bridge/parade-ps8622.c:491: + ret = drm_connector_init(bridge->drm, &ps8622->connector, &ps8622_connector_funcs, DRM_MODE_CONNECTOR_LVDS); But this seems unrelated to your changes - so should be ignored. Browsed the patch and throw it after my build check script. All looked good. Acked-by: Sam Ravnborg <sam@ravnborg.org> Sam

There are about 550 hits on 'struct drm_device *drm', so I gathered that it's the most common alternative to just naming it 'dev' (at about 4.5k hits in the codebase). There's also 'ddev', 'drm_dev', 'drmdev' with few hits. > > What about attached_dev or consumer_dev or encoder_dev? Those would be more descriptive, if you think it's worth sidestepping the above convention a bit.

I don't mind either way. Well, I don't have a say on these things, but it's worth considering a more descriptive name IMHO. I also wonder why that field is there in the first place. Invoking drm_bridge_attach() sets the encoder and its dev field for the bridge. [1] Could the dev field be removed and all users refer to encoder->dev instead? If so, it seems like the better way to go.
