From d5803c7319f5cc79afda066e2c8b9c61436b43df Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 24 Sep 2019 13:56:47 +1000 Subject: xics: Eliminate 'reject', 'resend' and 'eoi' class hooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently ics_reject(), ics_resend() and ics_eoi() indirect through class methods. But there's only one implementation of each method, the one in TYPE_ICS_SIMPLE. TYPE_ICS_BASE has no implementation, but it's never instantiated, and has no other subtypes. So clean up by eliminating the method and just having ics_reject(), ics_resend() and ics_eoi() contain the logic directly.
