From b771a5687d61a4b9834ed92602585d0cf9e71bca Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Mar 2020 15:49:27 +0100 Subject: drm/bochs: Drop explicit drm_mode_config_cleanup Instead rely on the automatic clean, for which we just need to check that drm_mode_config_init succeeded. To avoid an inversion in the cleanup we also have to move the dev_private allocation over to drmm_kzalloc. This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Acked-by: Gerd Hoffmann Acked-by: Sam Ravnborg Cc: Sam Ravnborg Cc: Thomas Zimmermann Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-29-daniel.vetter@ffwll.ch --- drivers/gpu/drm/bochs/bochs.h | 1 - drivers/gpu/drm/bochs/bochs_drv.c | 6 ++---- drivers/gpu/drm/bochs/bochs_kms.c | 14 +++++--------- 3 files changed, 7 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/bochs/bochs.h b/drivers/gpu/drm/bochs/bochs.h index 917767173ee6..e5bd1d517a18 100644 --- a/drivers/gpu/drm/bochs/bochs.h +++ b/drivers/gpu/drm/bochs/bochs.h @@ -92,7 +92,6 @@ void bochs_mm_fini(struct bochs_device *bochs); /* bochs_kms.c */ int bochs_kms_init(struct bochs_device *bochs); -void bochs_kms_fini(struct bochs_device *bochs); /* bochs_fbdev.c */ extern const struct drm_mode_config_funcs bochs_mode_funcs; diff --git a/drivers/gpu/drm/bochs/bochs_drv.c b/drivers/gpu/drm/bochs/bochs_drv.c index addb0568c1af..e18c51de1196 100644 --- a/drivers/gpu/drm/bochs/bochs_drv.c +++ b/drivers/gpu/drm/bochs/bochs_drv.c @@ -7,6 +7,7 @@ #include #include +#include #include "bochs.h" @@ -21,10 +22,7 @@ static void bochs_unload(struct drm_device *dev) { struct bochs_device *bochs = dev->dev_private; - bochs_kms_fini(bochs); bochs_mm_fini(bochs); - kfree(bochs); - dev->dev_private = NULL; } static int bochs_load(struct drm_device *dev) @@ -32,7 +30,7 @@ static int bochs_load(struct drm_device *dev) struct bochs_device *bochs; int ret; - bochs = kzalloc(sizeof(*bochs), GFP_KERNEL); + bochs = drmm_kzalloc(dev, sizeof(*bochs), GFP_KERNEL); if (bochs == NULL) return -ENOMEM; dev->dev_private = bochs; diff --git a/drivers/gpu/drm/bochs/bochs_kms.c b/drivers/gpu/drm/bochs/bochs_kms.c index e8cc8156d773..7f4bcfad87e9 100644 --- a/drivers/gpu/drm/bochs/bochs_kms.c +++ b/drivers/gpu/drm/bochs/bochs_kms.c @@ -134,7 +134,11 @@ const struct drm_mode_config_funcs bochs_mode_funcs = { int bochs_kms_init(struct bochs_device *bochs) { - drm_mode_config_init(bochs->dev); + int ret; + + ret = drmm_mode_config_init(bochs->dev); + if (ret) + return ret; bochs->dev->mode_config.max_width = 8192; bochs->dev->mode_config.max_height = 8192; @@ -160,11 +164,3 @@ int bochs_kms_init(struct bochs_device *bochs) return 0; } - -void bochs_kms_fini(struct bochs_device *bochs) -{ - if (!bochs->dev->mode_config.num_connector) - return; - - drm_mode_config_cleanup(bochs->dev); -} -- cgit v1.2.3
