From d9bfa935a9855664f5cea12131fa809fd56ff82c Mon Sep 17 00:00:00 2001 From: =?utf8?q?C=C3=A1ssio=20Gabriel?= Date: Mon, 6 Apr 2026 00:20:04 -0300 Subject: [PATCH] ALSA: gusclassic: add ISA suspend and resume callbacks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gusclassic still leaves its ISA PM callbacks disabled because the shared GF1 core had no suspend and resume path suitable for PM recovery. Wire the driver up to the new shared GUS suspend and resume helpers so a suspend/resume cycle restores usable GF1 operation without rerunning probe-only detection or tearing down the runtime bookkeeping kept by the card instance.
