From 8b0162a3dc5c30e862b7a73da29e32de3170f5e4 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 3 Nov 2008 11:27:38 +0100 Subject: ath5k: ignore the return value of ath5k_hw_noise_floor_calibration Noise floor calibration occasionally fails on Atheros hardware. This is not fatal and can happen if there's simply too much noise on the air. Ignoring the calibration error is the right thing to do here, because when the error is ignored, the hardware will still work, whereas if the error causes the driver to bail out of a bigger configuration function and does not configure the tx queues or the IMR (as is the case in reset.c), the hw no longer works properly until the next reset.
