From a0b8de350be458b33248e48b2174d9af8a4c4798 Mon Sep 17 00:00:00 2001 From: "Eugene A. Shatokhin" Date: Tue, 28 Jun 2011 23:04:51 -0400 Subject: [PATCH] ath5k: fix memory leak when fewer than N_PD_CURVES are in use We would free the proper number of curves, but in the wrong slots, due to a missing level of indirection through the pdgain_idx table. It's simpler just to try to free all four slots, so do that. Cc: stable@kernel.org Signed-off-by: Bob Copeland Signed-off-by: John W.
