From 993cac15d1194b7ff03da67993b82c4b21680739 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 28 Sep 2020 18:04:44 -0500 Subject: [PATCH] net: ipa: fix two mild warnings Fix two spots where a variable "channel_id" is unnecessarily redefined inside loops in "gsi.c". This is warned about if "W=2" is added to the build command. Note that this problem is harmless, so there's no need to backport it as a bugfix. Remove a comment in gsi_init() about waking the system; the GSI interrupt does not wake the system any more. Signed-off-by: Alex Elder Signed-off-by: David S.
