From 8d7e5908c0bcf8a0abc437385e58e49abab11a93 Mon Sep 17 00:00:00 2001 From: Amit Pundir Date: Fri, 16 Jul 2021 13:19:46 +0530 Subject: [PATCH] mailbox: qcom-ipcc: Enable loading QCOM_IPCC as a module This patch enables the qcom_ipcc driver to be loaded as a module. IPCC is fairly core to system, so as such it should never be unloaded. It registers as a mailbox + irq controller and the irq controller drivers in kernel are not supposed to be unloaded as they don't have the visibility over the clients consuming the irqs. Hence adding supress_bind_attrs to disable bind/unbind via sysfs.
