From 662845057f2d063461c88a97b737ec7f66daece0 Mon Sep 17 00:00:00 2001 From: Alexey Khoroshilov Date: Sat, 19 Jan 2013 16:56:34 +0400 Subject: [PATCH] iwlegacy: don't return zero on failure paths in il4965_pci_probe() If hardware is not ready, il4965_pci_probe() breaks off initialization, deallocates all resources, but returns zero. The patch adds -EIO as return value in this case. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: John W.
