From 155ab65c2e10b7bdd4d54d14d74ec2eb8d5db3fe Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 4 Aug 2022 10:03:21 +0300 Subject: [PATCH] wifi: cfg80211: debugfs: fix return type in ht40allow_map_read() [ Upstream commit d776763f48084926b5d9e25507a3ddb7c9243d5e ] The return type is supposed to be ssize_t, which is signed long, but "r" was declared as unsigned int. This means that on 64 bit systems we return positive values instead of negative error codes.
