From 6ebc22e6d06760466859b79d7b3b3edad264a230 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 13 May 2010 21:58:56 +0200 Subject: drivers/gpu/drm: Use kzalloc Use kzalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // Signed-off-by: Julia Lawall Reviewed-by: Corbin Simpson Reviewed-by: Matt Turner Signed-off-by: Dave Airlie --- drivers/gpu/drm/drm_auth.c | 3 +-- drivers/gpu/drm/drm_dma.c | 4 +--- drivers/gpu/drm/drm_fops.c | 3 +-- drivers/gpu/drm/savage/savage_bci.c | 3 +-- 4 files changed, 4 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/drm_auth.c b/drivers/gpu/drm/drm_auth.c index 932b5aa96a67..3f46772f0cb2 100644 --- a/drivers/gpu/drm/drm_auth.c +++ b/drivers/gpu/drm/drm_auth.c @@ -79,10 +79,9 @@ static int drm_add_magic(struct drm_master *master, struct drm_file *priv, struct drm_device *dev = master->minor->dev; DRM_DEBUG("%d\n", magic); - entry = kmalloc(sizeof(*entry), GFP_KERNEL); + entry = kzalloc(sizeof(*entry), GFP_KERNEL); if (!entry) return -ENOMEM; - memset(entry, 0, sizeof(*entry)); entry->priv = priv; entry->hash_item.key = (unsigned long)magic; mutex_lock(&dev->struct_mutex); diff --git a/drivers/gpu/drm/drm_dma.c b/drivers/gpu/drm/drm_dma.c index 13f1537413fb..252cbd74df0e 100644 --- a/drivers/gpu/drm/drm_dma.c +++ b/drivers/gpu/drm/drm_dma.c @@ -47,12 +47,10 @@ int drm_dma_setup(struct drm_device *dev) { int i; - dev->dma = kmalloc(sizeof(*dev->dma), GFP_KERNEL); + dev->dma = kzalloc(sizeof(*dev->dma), GFP_KERNEL); if (!dev->dma) return -ENOMEM; - memset(dev->dma, 0, sizeof(*dev->dma)); - for (i = 0; i <= DRM_MAX_ORDER; i++) memset(&dev->dma->bufs[i], 0, sizeof(dev->dma->bufs[0])); diff --git a/drivers/gpu/drm/drm_fops.c b/drivers/gpu/drm/drm_fops.c index 9d532d7fdf59..e7aace20981f 100644 --- a/drivers/gpu/drm/drm_fops.c +++ b/drivers/gpu/drm/drm_fops.c @@ -243,11 +243,10 @@ static int drm_open_helper(struct inode *inode, struct file *filp, DRM_DEBUG("pid = %d, minor = %d\n", task_pid_nr(current), minor_id); - priv = kmalloc(sizeof(*priv), GFP_KERNEL); + priv = kzalloc(sizeof(*priv), GFP_KERNEL); if (!priv) return -ENOMEM; - memset(priv, 0, sizeof(*priv)); filp->private_data = priv; priv->filp = filp; priv->uid = current_euid(); diff --git a/drivers/gpu/drm/savage/savage_bci.c b/drivers/gpu/drm/savage/savage_bci.c index bff6fc2524c8..2d0c9ca484c5 100644 --- a/drivers/gpu/drm/savage/savage_bci.c +++ b/drivers/gpu/drm/savage/savage_bci.c @@ -539,11 +539,10 @@ int savage_driver_load(struct drm_device *dev, unsigned long chipset) { drm_savage_private_t *dev_priv; - dev_priv = kmalloc(sizeof(drm_savage_private_t), GFP_KERNEL); + dev_priv = kzalloc(sizeof(drm_savage_private_t), GFP_KERNEL); if (dev_priv == NULL) return -ENOMEM; - memset(dev_priv, 0, sizeof(drm_savage_private_t)); dev->dev_private = (void *)dev_priv; dev_priv->chipset = (enum savage_family)chipset; -- cgit v1.2.2
