selftests/hid: fix compilation when bpf_wq and hid_device are not exported
commit 5d4c6c132ea9a967d48890dd03e6a786c060e968 upstream. This can happen in situations when CONFIG_HID_SUPPORT is set to no, or some complex situations where struct bpf_wq is not exported. So do the usual dance of hiding them before including vmlinux.h, and then redefining them and make use of CO-RE to have the correct offsets. Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202603111558.KLCIxsZB-lkp@intel.com/ Fixes: fe8d561db3e8 ("selftests/hid: add wq test for hid_bpf_input_report()") Cc: stable@vger.kernel.org Acked-by: Jiri Kosina <jkosina@suse.com> Reviewed-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Signed-off-by: Benjamin Tissoires <bentiss@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
