From 215d530887bdfeba5ec82a800e6b0ced64bb8b48 Mon Sep 17 00:00:00 2001 From: Shaun Ruffell Date: Mon, 3 Jan 2011 18:27:05 +0000 Subject: [PATCH] dahdi: Introduce dahdi_kasprintf for pre 2.6.12 kernels. kasprintf will be used in upcoming changes and it's not supported on RHEL4 kernels. This change essentially backports it.
