From 7eff2e7a8b65c25920207324e56611150eb1cd9a Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Tue, 14 Aug 2007 15:15:12 +0200 Subject: Driver core: change add_uevent_var to use a struct This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.
