Description
In the Linux kernel, the following vulnerability has been resolved:
mfd: sm501: Fix reference leak on failed device registration
When platform_device_register() fails in sm501_register_device(), the
embedded struct device in pdev has already been initialized by
device_initialize(), but the failure path only reports the error and
returns without dropping the device reference for the current platform
device:
sm501_register_device()
-> platform_device_register(pdev)
-> device_initialize(&pdev->dev)
-> setup_pdev_dma_masks(pdev)
-> platform_device_add(pdev)
This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before returning the error.
The issue was identified by a static analysis tool I developed and
confirmed by manual review.
