commit: bf7e1abe434ba9e22e8dc04a4cba4ab504b788b8 From: Stanislaw Gruszka <[email protected]> Date: Thu, 25 Oct 2012 09:51:39 +0200 Subject: rt2800: validate step value for temperature compensation
Some hardware has correct (!= 0xff) value of tssi_bounds[4] in the EEPROM, but step is equal to 0xff. This results on ridiculous delta calculations and completely broke TX power settings.
