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.
