There is a "if (err)" check earlier, so the "if (err < 0)"
check that this patch removing is unnecessary. It was my overlook
when making adjustments to the bpf_struct_ops_prepare_trampoline()
such that the caller does not have to worry about the new page when
the function returns error.
Fixes: 187e2af05a ("bpf: struct_ops supports more than one page for trampolines.")

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.
