Bug description:
[Impact]
Some uses of kernel_read_file_from_fd may lead to a WARN when the file is
not opened for reading.
The WARNING, however, is not present on earlier kernels, which will return
a different error code. The fix, however, has been applied to upstream stable
and may be worth so tests can PASS without much change.
[Fix/Backport]
The fix is trivial, but the backport for Focal and Bionic was picked up
from 5.4.y upstream stable tree, because the function was moved to a
different file.
[Test case]
The finit_module02 test case from LTP covers this.
[Potential regression]
kernel_read_file_from_fd is used for module loading and kexec, so there is
where regressions might show up.
