"struct drm_edid" is the safe and recommended alternative to "struct edid".
Rename the member to make sure that no usage sites are missed, as "struct drm_edid" has some restrictions, for example it can not be used with kfree(). Signed-off-by: Thomas Weißschuh <li...@weissschuh.net> --- Changes in v2: - Simplify some logic as drm_edid_*()-APIs can handle NULL - Correctly use drm_edid_read_switcheroo() - Link to v1: https://lore.kernel.org/r/20240818-radeon-drm_edid-v1-1-4b7fdd191...@weissschuh.net --- This is only compile-tested. --- drivers/gpu/drm/radeon/radeon_audio.c | 4 +-- drivers/gpu/drm/radeon/radeon_combios.c | 4 +-- drivers/gpu/drm/radeon/radeon_connectors.c | 56 +++++++++++++----------------- drivers/gpu/drm/radeon/radeon_mode.h | 5 ++- 4 files changed, 31 insertions(+), 38 deletions(-) diff --git a/drivers/gpu/drm/radeon/radeon_audio.c b/drivers/gpu/drm/radeon/radeon_audio.c index 47aa06a9a942..59d0e47c94d0 100644 --- a/drivers/gpu/drm/radeon/radeon_audio.c +++ b/drivers/gpu/drm/radeon/radeon_audio.c @@ -311,7 +311,7 @@ static void radeon_audio_write_sad_regs(struct drm_encoder *encoder) if (!connector) return;
