CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

Wolfram Sang c5bd2a712a drivers/leds/leds-tca6507.c: remove obsolete cleanup for clientdata
A few new i2c-drivers came into the kernel which clear the
clientdata-pointer on exit or error.  This is obsolete meanwhile, the
core will do it.

Dan Carpenter 920c4f4c36 drivers/leds/leds-tca6507.c: cleanup error handling in tca6507_probe()
Just a small tidy-up.

1) There is a NULL dereference if the tca allocation fails.
2) The call to cancel_work_sync() isn't needed because we haven't
   scheduled any work.
3) The call to i2c_set_clientdata() isn't needed because the core
   handles that automatically if probe() fails.
4) I added some curly braces for style reasons.

NeilBrown a6d511e515 leds: add driver for TCA6507 LED controller
TI's TCA6507 is the LED driver in the GTA04 Openmoko motherboard.  The
driver provides full support for brightness levels and hardware blinking.

This driver can drive each of 7 outputs as an LED or a GPIO output,
and provides hardware-assist blinking.
