Wysocki" , Len Brown , linux-kernel@vger.kernel.org Subject: [PATCH] ACPI / GED: use late init to allow other drivers init Date: Fri, 21 Apr 2017 18:28:24 -0400 Message-Id: <1492813704-32280-1-git-send-email-okaya@codeaurora.org> X-Mailer: git-send-email 1.9.1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 910 Lines: 29 GED driver is currently set up as a platform driver. On modern operating systems, most of the drivers are compiled as kernel modules. It is possible that a GED interrupt event is received and the driver such as GHES/GPIO/I2C to service it is not available yet. To accommodate this use case, delay GED driver load to the late init phase.
