From 522536f6b24e63ac946259af65224f107dff7857 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Wed, 28 Jun 2006 19:11:21 -0500 Subject: [PATCH] [PATCH] bcm43xx-softmac: Fix an off-by-one condition in handle_irq_noise An assert statement near the start of handle_irq_noise in the softmac version of bcm43xx_main.c is there to protect against out of bound addressing using variable bcm->noisecalc.nr_samples. The arrays in question have a dimension of 8, thus the value must be < 8. Signed-Off-By: Larry.Finger Signed-off-by: John W.
