From a96ca105a68bc66c564accdfeb81c36e1d5d46b3 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Mon, 17 Dec 2007 09:47:17 +1000 Subject: mga_dma: return 'err' not just zero from mga_do_cleanup_dma() While reading some code I stumbled across the use of 'err' in drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small problem. The variable is only used inside #if __OS_HAS_AGP which is fine, but all that ever happens is an assignment to the variable - it is never actually used for anything. The variable is nicely initialized to zero which is also what the return statement at the end of function returns (always at the moment). It looks to me like that function should be returning 'err' instead of always just returning 0. Here's a patch to do that.
