This fixes the expression in the driver to do the correct thing,
not that I think anyone would send SND_* without EV_SND.

Apparently these might be called under atomic context,
and i2c operations may sleep. BUG found by

When the registration fails, we need to release the memory we allocated.
Also we need to save the error from led_classdev_register and propagate
it up, else we'll return success, even if we failed.

NXP pca9532 is a LED dimmer/controller attached to i2c bus.  It allows
attaching upto 16 leds which can either be on, off or dimmed and/or blinked
with the two PWM modulators available.

This driver is a "new-style" i2c driver that adheres to the driver model and
implements the led framework api.  Since the leds connected to the driver are
platform specific, it is only useful when platform data is passed to the
driver to define what leds are connected to which pins.
