Subject: [PATCH] sky2: Don't try to turn led off in sky2_down()

There are a few problems with the following line of code in sky2_down()

     sky2_write16(hw, B0_Y2LED, LED_STAT_OFF);

 * It doesn't specify which port's LED to turn off.
 * We don't turn send LED_STAT_ON on in sky2_up()
 * B0_LED is 0x0006 in the vendor driver, but 0x0005 in sky2.
   B0_LED is right next to B0_POWER_CTRL, so this is possibly
   accounts for the device being accidently powered down as
   reported by Rene Mayrhofer.
