wl1271: refactor debugfs function generation code
refactor wl1271_debugfs by using a format© function, instead of duplicating the code for each generated function. this change reduces about 3Kb from wl1271.ko Signed-off-by: Eliad Peller <eliad@wizery.com> Reviewed-by: Luciano Coelho <luciano.coelho@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
