[PATCH] bcm43xx: fix unexpected LED control values in BCM4303 sprom
The bcm43xx driver uses 4 locations in the devices sprom to determine the behavior of the leds. Certain defaults are assigned if all bits are set in those locations. On at least one BCM4303 chip, the sprom contains values other than the default, which executes an assertion placed in the default case of a following switch statement. This patch makes the leds on the above mentioned interface behave correctly. In addition, it limits the number of logged messages to 20 for the case of unexpected values in the sprom locations.
