Subject: Re: [PATCH] net: marvell: fix a missing check of acpi_match_device

From: Kangjie Lu <>
Date: Wed, 26 Dec 2018 00:31:08 -0600

> When acpi_match_device fails, its return value is NULL. Directly using
> the return value without a check may result in a NULL-pointer
> dereference. The fix checks if acpi_match_device fails, and if so,
> returns -EINVAL.
