The BSD-3-Clause license still applies to this file, even though the overall project license is GPL. This shouldn't be a problem as these licenses are compatible. You could clarify the licensing of this file in the project by using a compound SPDX license expression (see https://spdx.org/spdx-specification-21-web-version#h.twlc0ztnng3b)

e.g.

SPDX-License-Identifier: (GPL-2.0+ AND BSD-3-Clause)

This would indicate that both licenses must be complied with. It's also possible to use "OR" to indicate that either license may be used, but I guess that's probably not what you want in this case.

Regards

Dan.
