leds: pwm: Clear the led structure before parsing each child node
I defined 2 leds in the device tree, in the 1st led node, the
max-brightness is set to 248, while in the 2nd led node, I
mis-spelled the max-brightness to max-brighttness, but the driver
is still able to get the max-brightness 248 for the 2nd node, that
is because the led structure is not cleared before parsing each child
node.
pwmleds {
compatible = "pwm-leds";
pwm-green {
...
max-brightness = <248>;
};
pwm-red {
...
max-brighttness = <128>;
};
