drm/hisilicon/hibmc: select CONFIG_DRM_DISPLAY_DP_HELPER

Without the DP helper code, the newly added displayport support causes a link failure: x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_aux.o: in function `hibmc_dp_aux_init': dp_aux.c:(.text+0x37e): undefined reference to `drm_dp_aux_init' x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.o: in function `hibmc_dp_link_set_pattern': dp_link.c:(.text+0xae): undefined reference to `drm_dp_dpcd_write' x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.o: in function `hibmc_dp_link_get_adjust_train': dp_link.c:(.text+0x121): undefined reference to `drm_dp_get_adjust_request_voltage' x86_64-linux-ld: dp_link.c:(.text+0x12e): undefined reference to `drm_dp_get_adjust_request_pre_emphasis' x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.o: in function `hibmc_dp_link_training': dp_link.c:(.text+0x2b0): undefined reference to `drm_dp_dpcd_write' x86_64-linux-ld: dp_link.c:(.text+0x2e3): undefined reference to `drm_dp_dpcd_write' Add both DRM_DISPLAY_DP_HELPER and DRM_DISPLAY_HELPER, which is in turn required by the former.

drm: remove driver date from struct drm_driver and all drivers

2024-12-05T10:35:42Z

We stopped using the driver initialized date in commit 7fb8af6798e8 ("drm: deprecate driver date") and (eventually) started returning "0" for drm_version ioctl instead. Finish the job, and remove the unused date member from struct drm_driver, its initialization from drivers, along with the common DRIVER_DATE macros. v2: Also update drivers/accel (kernel test robot) Reviewed-by: Javier Martinez Canillas Acked-by: Alex Deucher Acked-by: Simon Ser Acked-by: Jeffrey Hugo Acked-by: Lucas De Marchi Acked-by: Dmitry Baryshkov # msm Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/1f2bf2543aed270a06f6c707fd6ed1b78bf16712.1733322525.git.jani.nikula@intel.com Signed-off-by: Jani Nikula

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43Z

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds
