From 1d3c6f86fd3f8b88c707f56d8c3f94e014b40e83 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Thu, 26 Mar 2020 22:44:58 +0000 Subject: [PATCH] soc: qcom: rpmh: Allow RPMH driver to be loaded as a module This patch allow the rpmh driver to be loaded as a permenent module. Meaning it can be loaded from a module, but then cannot be unloaded. Ideally, it would include a remove hook and related logic, but the rpmh driver is fairly core to the system, so once its loaded with almost anythign else to get the system to go, the dependencies are not likely to ever also be removed. So making it a permenent module at least improves things slightly over requiring it to be a built in driver.
