From 71a33465726e4125f5ef33705ce5bc7ec1bf5b1f Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 15 Dec 2025 15:16:32 +0100 Subject: tee: Add probe, remove and shutdown bus callbacks to tee_client_driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a bus specific probe, remove and shutdown function. For now this only allows to get rid of a cast of the generic device to a tee_client device in the drivers and changes the remove prototype to return void---a non-zero return value is ignored anyhow. The objective is to get rid of users of struct device_driver callbacks .probe(), .remove() and .shutdown() to eventually remove these. Until all tee_client drivers are converted this results in a runtime warning about the drivers needing an update because there is a bus probe function and a driver probe function.
