From 5242a5444e0b6464d7455beb55d936dd192b5e9d Mon Sep 17 00:00:00 2001 From: Arend Van Spriel Date: Mon, 22 Jan 2018 21:46:39 +0100 Subject: [PATCH] brcmfmac: assure bcdc dcmd api does not return value > 0 The protocol layer api defines callbacks for dongle commands. Although not really well documented these should only return an error code in case of an error, or 0 upon success. In the bcdc protocol it can return value above 0 and we carry a fix in the caller of the protocol layer api. This patch makes it adhere to the intent of the api as described above.
