From 589aadd6577bad74cf48d35ed2c0258f3ce9a4d3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 17 Jan 2018 16:18:27 -0800 Subject: [PATCH] Input: synaptics-rmi4 - do not delete interrupt memory too early commit a1ab69021a584d952e6548a44b93760547b1b6b5 upstream. We want to free memory reserved for interrupt mask handling only after we free functions, as function drivers might want to mask interrupts. This is needed for the followup patch to the F03 that would implement unmasking and masking interrupts from the serio pass-through port open() and close() methods.
