[PATCH 0/2] Fix LED GPIO trigger behavior

[Kun Yi]

*** BLURB HERE ***
Hello there,

I recently tested ledtrig-gpio on an embedded controller and one of the
issues I had involve not requesting the user input pin as GPIO.

In many embedded systems, a pin could be muxed as several functions, and
requesting the pin as GPIO is necessary to let pinmux select the pin as
a GPIO instead of, say an I2C pin. I'd like to learn whether it is appropriate
to assume user of ledtrig-gpio really intends to use GPIOs and not some
weird pins that are used as other functions.

Kun Yi (2):
  ledtrig-gpio: Request user input pin as GPIO
  ledtrig-gpio: 0 is a valid GPIO number
