From f43084498b42c11054a8218b445ff6491c35bcdc Mon Sep 17 00:00:00 2001 From: Shanyu Zhao Date: Tue, 11 May 2010 15:25:03 -0700 Subject: iwlwifi: do not clear data after chain noise calib Chain noise calibration data are cleared after the calibration is done in iwlagn_gain_computation() and iwl4965_gain_computation(). This cause the debugfs entries for those data useless. To provide valid debugging info, clear those data right before starting the calibration instead.
