Hello Himangi Saraogi,
The patch 9f7b23ce88e9: "usb: phy: phy-gpio-vbus-usb: use devm_
functions" from Jun 4, 2014, leads to the following static checker
warning:
drivers/usb/phy/phy-gpio-vbus-usb.c:264 gpio_vbus_probe()
warn: passing devm_ allocated variable to kfree. 'gpio_vbus'
drivers/usb/phy/phy-gpio-vbus-usb.c
255
256 gpio_vbus = devm_kzalloc(&pdev->dev, sizeof(struct gpio_vbus_data),
257 GFP_KERNEL);
258 if (!gpio_vbus)
259 return -ENOMEM;
260
261 gpio_vbus->phy.otg = devm_kzalloc(&pdev->dev, sizeof(struct usb_otg),
262 GFP_KERNEL);
263 if (!gpio_vbus->phy.otg) {
264 kfree(gpio_vbus);
^^^^^^^^^
Double free on error.
265 return -ENOMEM;
266 }
267
regards,
dan carpenter
