From 9c6ead570c6b88b865fca15bdc0d09e2d90d2130 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Thu, 7 Jun 2012 23:39:23 +0300 Subject: wlcore: export raw binary with the FW statistics in debugfs Instead of parsing all the binary data returned by the firmware, we should simply export the binary and let the userspace do the parsing. This commit adds a new file to debugfs to do that.
