Linus Torvalds cb9b4c3403 * pca955x: Add HW blink support, utilizing PWM0. It supports one frequency
across all blinking LEDs and falls back to software blink if different
     frequencies are requested.
 
   * trigger: netdev: Allow configuring LED blink interval via .blink_set
     even when HW offload (.hw_control) is enabled.
   * led-core: Fix a race condition where a quick LED_OFF followed by another
     brightness set could leave the LED off incorrectly, especially
     noticeable after the introduction of the ordered workqueue.
