From d1530f94446bf69599664b0341be35317e18b8b5 Mon Sep 17 00:00:00 2001 From: Romain Forlot Date: Mon, 25 Nov 2019 15:04:07 +0100 Subject: socketcan-bcm: Fix wrongly opened socket This commit fixes a problem once a bcm socket has been opened but the following ioctl failed. Before we still return the socket number instead of returning a negative value as error. This resulted in problem because the subscription was considered as valid and binding was continuing using the closed file descriptor.
