From a4282717c102aef2bfab1d947c392de4d8abc0ec Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 14 Dec 2006 15:51:23 -0800 Subject: [AX.25]: Fix unchecked ax25_linkfail_register uses ax25_linkfail_register uses kmalloc and the callers were ignoring the error value. Rewrite to let the caller deal with the allocation. This allows the use of static allocation of kmalloc use entirely. Signed-off-by: Ralf Baechle Signed-off-by: David S.
