From: Julia Lawall <julia.law...@lip6.fr> devm_kfree should not have to be explicitly used. devm_regmap_init_i2c also does not require an explicit free.
The semantic patch that fixes the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,d; @@ x = devm_kzalloc(...) ... ?-devm_kfree(d,x); // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- v2: Removed over-eager optimization of some error-handling code. drivers/mfd/88pm800.c | 5 +---- drivers/mfd/88pm80x.c | 19 +++---------------- 2 files changed, 4 insertions(+), 20 deletions(-) diff --git a/drivers/mfd/88pm800.c b/drivers/mfd/88pm800.c index b67a301..a2e5bd8 100644 --- a/drivers/mfd/88pm800.c +++ b/drivers/mfd/88pm800.c @@ -530,7 +530,7 @@ static int __devinit pm800_probe(struct i2c_client *client, ret = device_800_init(chip, pdata); if (ret) { dev_err(chip->dev, "%s id 0x%x failed!\n", __func__, chip->id); - goto err_800_init; + goto err_subchip_alloc; } ret = pm800_pages_init(chip); @@ -545,8 +545,6 @@ static int __devinit pm800_probe(struct i2c_client *client, err_page_init: mfd_remove_devices(chip->dev); device_irq_exit_800(chip); -err_800_init: - devm_kfree(&client->dev, subchip); err_subchip_alloc: pm80x_deinit(client); out_init: @@ -561,7 +559,6 @@ static int __devexit pm800_remove(struct i2c_client *client) device_irq_exit_800(chip); pm800_pages_exit(chip); - devm_kfree(&client->dev, chip->subchip); pm80x_deinit(client); diff --git a/drivers/mfd/88pm80x.c b/drivers/mfd/88pm80x.c index cd0bf52..ae2bb85 100644 --- a/drivers/mfd/88pm80x.c +++ b/drivers/mfd/88pm80x.c @@ -48,14 +48,12 @@ int __devinit pm80x_init(struct i2c_client *client, ret = PTR_ERR(map); dev_err(&client->dev, "Failed to allocate register map: %d\n", ret); - goto err_regmap_init; + return ret; } chip->id = id->driver_data; - if (chip->id < CHIP_PM800 || chip->id > CHIP_PM805) { - ret = -EINVAL; - goto err_chip_id; - } + if (chip->id < CHIP_PM800 || chip->id > CHIP_PM805) + return -EINVAL; chip->client = client; chip->regmap = map; @@ -82,19 +80,11 @@ int __devinit pm80x_init(struct i2c_client *client, } return 0; - -err_chip_id: - regmap_exit(map); -err_regmap_init: - devm_kfree(&client->dev, chip); - return ret; } EXPORT_SYMBOL_GPL(pm80x_init); int pm80x_deinit(struct i2c_client *client) { - struct pm80x_chip *chip = i2c_get_clientdata(client); - /* * workaround: clear the dependency between pm800 and pm805. * would remove it after HW chip fixes the issue. @@ -104,9 +94,6 @@ int pm80x_deinit(struct i2c_client *client) else g_pm80x_chip = NULL; - regmap_exit(chip->regmap); - devm_kfree(&client->dev, chip); - return 0; } EXPORT_SYMBOL_GPL(pm80x_deinit); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
