From: Alex Elder Date: Mon, 28 Sep 2020 23:04:44 +0000 (-0500) Subject: net: ipa: fix two mild warnings X-Git-Tag: baikal/mips/sdk5.9~12462^2~119^2~2 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=645082a64db038ef67974542835e426f1950eceb;p=kernel.git 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.
