Re: [PATCH v2 2/4] drm/panel: Initialise panel dev and funcs through drm_panel_init()

On Fri, Aug 23, 2019 at 10:32:43PM +0300, Laurent Pinchart wrote:

Instead of requiring all drivers to set the dev and funcs fields of drm_panel manually after calling drm_panel_init(), pass the data as arguments to the function. This simplifies the panel drivers, and will help future refactoring when adding new arguments to drm_panel_init().

The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection to verify that no call to drm_panel_init() with a single argument still exists.

@@ expression panel; expression device; identifier ops; @@ drm_panel_init(&panel

• , device, &ops

); ... ( -panel.dev = device; -panel.funcs = &ops; | -panel.funcs = &ops; -panel.dev = device; )

Thanks, applied to drm-misc-next. Nice use of Coccinelle.
