drm/<drivers>: Constify struct drm_driver
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch
