From aa2b17708380ca48946a9ad97907f54032cf48fc Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 24 Jan 2013 14:12:07 +0100 Subject: [PATCH] iwlwifi: fix calibration parser The firmware TLV for calibration data isn't really a u64, but two u32 values. Define a struct for that and change the parser.
