This is a note to let you know that I've just added the patch titled drm/panel: Initialise panel dev and funcs through drm_panel_init() to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-panel-initialise-panel-dev-and-funcs-through-drm.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f849202961ea5bcb40ab2762d74ce17555110c64 Author: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> Date: Fri Aug 23 22:32:43 2019 +0300 drm/panel: Initialise panel dev and funcs through drm_panel_init() [ Upstream commit 6dbe0c4b0fc0646442b2b1580d022404e582fd7b ] 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 ); ...
