x86/entry: Fix kernel-doc warning

Daniel Sneddon · Ingo Molnar · commit 0f6750b15ffd · 2025-02-25T23:12:58.000+01:00
The do_int80_emulation() function is missing a kernel-doc formatted description of its argument. This is causing a warning when building with W=1. Add a brief description of the argument to satisfy kernel-doc.
