From e9877d4ef856c7e8c66e942baa94dd0dde09b787 Mon Sep 17 00:00:00 2001 From: Sergey Ryazanov Date: Tue, 7 Dec 2021 12:21:37 +0300 Subject: [PATCH] net: wwan: iosm: consolidate trace port init code Move the channel related structures initialization from ipc_imem_channel_init() to ipc_trace_init() and call it directly. On the one hand, this makes the trace port initialization symmetric to the deitialization, that is, it removes the additional wrapper. On the other hand, this change consolidates the trace port related code into a single source file, what facilitates an upcoming disabling of this functionality by a user choise.
