From 264ddd077c72092178153fc32d510dcecff32eeb Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Sat, 30 May 2020 13:46:40 +0100 Subject: [PATCH] drm/auth: make drm_{set,drop}master_ioctl symmetrical Currently the ret handling is all over the place - with two redundant assignments and another one addressed earlier. Use the exact same flow in both functions. v2: straighten the code flow, instead of just removing the assignments Cc: David Airlie Cc: Daniel Vetter Cc: Sam Ravnborg Cc: Colin Ian King Signed-off-by: Emil Velikov Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200530124640.4176323-2-emil.l.velikov@gmail.com --- drivers/gpu/drm/drm_auth.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/drm_auth.c b/drivers/gpu/drm/drm_auth.c index 4c723e3a689c..f2d46b7ac6f9 100644 --- a/drivers/gpu/drm/drm_auth.c +++ b/drivers/gpu/drm/drm_auth.c @@ -215,7 +215,7 @@ drm_master_check_perm(struct drm_device *dev, struct drm_file *file_priv) int drm_setmaster_ioctl(struct drm_device *dev, void *data, struct drm_file *file_priv) { - int ret = 0; + int ret; mutex_lock(&dev->master_mutex); @@ -272,12 +272,15 @@ int drm_dropmaster_ioctl(struct drm_device *dev, void *data, if (ret) goto out_unlock; - ret = -EINVAL; - if (!drm_is_current_master(file_priv)) + if (!drm_is_current_master(file_priv)) { + ret = -EINVAL; goto out_unlock; + } - if (!dev->master) + if (!dev->master) { + ret = -EINVAL; goto out_unlock; + } if (file_priv->master->lessor != NULL) { DRM_DEBUG_LEASE("Attempt to drop lessee %d as master\n", file_priv->master->lessee_id); @@ -285,7 +288,6 @@ int drm_dropmaster_ioctl(struct drm_device *dev, void *data, goto out_unlock; } - ret = 0; drm_drop_master(dev, file_priv); out_unlock: mutex_unlock(&dev->master_mutex);
