Simple report descriptor override in HID: replace part of the report descriptor from a static definition in the bpf kernel program.

Note that this test should be run last because we disconnect/reconnect the device, meaning that it changes the overall uhid device.

You might want to add that in a comment right before:

@@ -329,6 +395,9 @@ void serial_test_hid_bpf(void) err = test_hid_raw_event(hid_skel, uhid_fd, sysfs_fd); ASSERT_OK(err, "hid");

• err = test_rdesc_fixup(hid_skel, uhid_fd, sysfs_fd);
• ASSERT_OK(err, "hid_rdesc_fixup");

There, so that you don't add another test after this later on in 5 years.

Anyway, just a nit:
