From a97fbc3ee3e2a536fafaff04f21f45472db71769 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 29 Oct 2025 17:33:30 +0100 Subject: syscore: Pass context data to callbacks Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J.
