KERNEL_VERSION: 2.6.32
SUBJECT: null derefernce in function __init yam_init_driver SUBSCRIBE:
In driver drivers/net/hamradio/yam.c in function __init
yam_init_driver:

1. If in line 1153 dev = NULL then we goto line 1154
2. In line 1155 we have null dereference of "dev->name"

1153 if (!dev) {
1154 printk(KERN_ERR "yam: cannot allocate net device
%s\n",
1155 dev->name);
1156 err = -ENOMEM;
1157 goto error;
1158 }
