From 0cb70ee4a6ee6b0a4b0e0f70a64a094c6fe05944 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Wed, 14 Aug 2024 13:22:25 +0800 Subject: [PATCH] virtio: rename virtio_config_enabled to virtio_config_core_enabled Following patch will allow the config interrupt to be disabled by a specific driver via another boolean. So this patch renames virtio_config_enabled and relevant helpers to virtio_config_core_enabled. Cc: Venkat Venkatsubra Cc: Gia-Khanh Nguyen Acked-by: Michael S.
