From 35b3ac470b982ded560e1b2ec9206a8d186c3459 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 10 Jan 2011 10:26:00 +0800 Subject: [PATCH] iwmc3200wifi: Return proper error for iwm_if_alloc In the case of alloc_netdev_mq failure and kmalloc failure, current implementation returns ERR_PTR(0). As a result, the caller of iwm_if_alloc does not catch the error by IS_ERR macro. Fix it by setting proper error code for ret variable in the failure cases.
