From 09f18afe766ea3f2c749e3af195bf65fde71b62e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Apr 2011 03:14:47 -0700 Subject: [PATCH] iwlagn: extend notification wait function A notification wait function is called with the command, but currently has no way of passing data back to the caller -- fix that by adding a void pointer to the function that can be used between the caller and the function.
