This patch fix checkpatch warnings concerning the possible duplication of an "out of memory" message. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr) @@ identifier f,print,l; expression e; constant char[] c; @@ e = \(kzalloc\|kmalloc\|devm_kzalloc\|devm_kmalloc\)(...); if (e == NULL) { <+... - print(...,c,...); ... when any ( goto l; | return ...; ) ...+> } Signed-off-by: Quentin Lambert <lambert.quentin@xxxxxxxxx> --- drivers/base/firmware_class.c | 1 - drivers/base/power/clock_ops.c | 4 +--- drivers/base/power/opp.c | 8 ++------ 3 files changed, 3 insertions(+), 10 deletions(-) diff --git a/drivers/base/firmware_class.c b/drivers/base/firmware_class.c index 58470c3..c3293f0 100644 --- a/drivers/base/firmware_class.c +++ b/drivers/base/firmware_class.c @@ -855,7 +855,6 @@ fw_create_instance(struct firmware *firmware, const char *fw_name, fw_priv = kzalloc(sizeof(*fw_priv), GFP_KERNEL); if (!fw_priv) { - dev_err(device, "%s: kmalloc failed\n", __func__); fw_priv = ERR_PTR(-ENOMEM); goto exit; } diff --git a/drivers/base/power/clock_ops.c b/drivers/base/power/clock_ops.c index d626576..7fdd017 100644 --- a/drivers/base/power/clock_ops.c +++ b/drivers/base/power/clock_ops.c @@ -81,10 +81,8 @@ static int __pm_clk_add(struct device *dev, const char *con_id, return -EINVAL; ce = kzalloc(sizeof(*ce), GFP_KERNEL); - if (!ce) { - dev_err(dev, "Not enough memory for clock entry.\n"); + if (!ce) return -ENOMEM; - } if (con_id) { ce->con_id = kstrdup(con_id, GFP_KERNEL); diff --git a/drivers/base/power/opp.c b/drivers/base/power/opp.c index 15bf299..677fb28 100644 --- a/drivers/base/power/opp.c +++ b/drivers/base/power/opp.c @@ -474,10 +474,8 @@ static int _opp_add_dynamic(struct device *dev, unsigned long freq, /* allocate new OPP node */ new_opp = kzalloc(sizeof(*new_opp), GFP_KERNEL); - if (!new_opp) { - dev_warn(dev, "%s: Unable to create new OPP node\n", __func__); + if (!new_opp) return -ENOMEM; - } /* Hold our list modification lock here */ mutex_lock(&dev_opp_list_lock); @@ -695,10 +693,8 @@ static int _opp_set_availability(struct device *dev, unsigned long freq, /* keep the node allocated */ new_opp = kmalloc(sizeof(*new_opp), GFP_KERNEL); - if (!new_opp) { - dev_warn(dev, "%s: Unable to create OPP\n", __func__); + if (!new_opp) return -ENOMEM; - } mutex_lock(&dev_opp_list_lock); -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
