[PATCH v1 1/1] leds: core: Refactor led_update_brightness() to use standard pattern

[PATCH v1 1/1] leds: core: Refactor led_update_brightness() to use standard pattern

[Andy Shevchenko]

The standard conditional pattern is to check for errors first and
bail out if any. Refactor led_update_brightness() accordingly.

While at it, drop unneeded assignment and return 0 unconditionally
on success.
