From 80cd69203c3ad5f2ecf7d01cec4a10ed15613682 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Tue, 31 Jul 2007 00:39:05 -0700 Subject: [PATCH] ipmi: Fix mem leak in try_init_dmi() This is only called at init time and only happens if the BIOS screws something up, so the leak is slight and it is probably not worth sending to 2.6.22.x. The driver would not initialize the interface in the case, and I have no reports of this happening. I have booted and run tests on a system with this patch. Note that the original patch was munged by the mailer, here's a new one. If we ever hit the "default:" case in the switch in try_init_dmi(), then we'll leak the storage allocated with kzalloc() and assigned to 'info'.
