From 2ca7e30d3b1ee370c96201e58f8c05ba2bdcd6d2 Mon Sep 17 00:00:00 2001 From: Bhaumik Bhatt Date: Wed, 18 Nov 2020 10:20:25 -0800 Subject: [PATCH] net: qrtr: Unprepare MHI channels during remove Reset MHI device channels when driver remove is called due to module unload or any crash scenario. This will make sure that MHI channels no longer remain enabled for transfers since the MHI stack does not take care of this anymore after the auto-start channels feature was removed.
