I'll consider it, depending on whether it makes the overall > patchset easier or harder to read. tbh since the goal is to embed the structures (I assume) I wouldn't bother. As soon as it's embedded it's the same for the compiler. If you flip some of the parameters I'd wait until the embedding is completely, otherwise you have a pile of churn again because of the switch from pointer to embedded structure. -Daniel > > Best regards > Thomas > > > > > Sam > > > > > > The ast variable in ast_crtc_helperatomic_check() is unused, > > s/ast_crtc_helperatomic_check/ast_crtc_helper_atomic_check/ > >> so removed it. > >> > >> Signed-off-by: Thomas Zimmermann <tzimmermann@xxxxxxx> > > Acked-by: Sam Ravnborg <sam@xxxxxxxxxxxx> > > > >> --- > >> drivers/gpu/drm/ast/ast_dp501.c | 24 +++++++++---------- > >> drivers/gpu/drm/ast/ast_drv.h | 5 ++++ > >> drivers/gpu/drm/ast/ast_main.c | 10 ++++---- > >> drivers/gpu/drm/ast/ast_mode.c | 41 ++++++++++++++++----------------- > >> drivers/gpu/drm/ast/ast_post.c | 16 ++++++------- > >> 5 files changed, 50 insertions(+), 46 deletions(-) > >> > >> diff --git a/drivers/gpu/drm/ast/ast_dp501.c b/drivers/gpu/drm/ast/ast_dp501.c > >> index 98cd69269263f..4b85a504825a2 100644 > >> --- a/drivers/gpu/drm/ast/ast_dp501.c > >> +++ b/drivers/gpu/drm/ast/ast_dp501.c > >> @@ -10,7 +10,7 @@ MODULE_FIRMWARE("ast_dp501_fw.bin");
