The remove callback is only ever called after .probe() returned successfully. After that get_stmmac_bsp_priv() always return non-NULL. Side note: The early exit would also be a bug because the return value of qcom_ethqos_remove() is ignored by the device core and the device is unbound unconditionally. So exiting early resulted in a dangerous resource leak as all devm allocated resources (some memory and the register mappings) are freed but the network device stays around. Using the network device afterwards probably oopses.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
