[PATCH 1/5] ARM: dts: imx23-evk: enable USB PHY and controller

[Otavio Salvador]

The i.MX23EVK board provides a USB port so the USB PHY and controller
need to be enabled for it to be usable.

[PATCH 2/5] ARM: mxs-lradc: Simplify mxs_lradc_trigger_init error handle

[Otavio Salvador]

As we have a 'ret' variable with the iio_trigger_register return, this
can be used as result.
