There is no need to keep the FSF address inside each file. Moreover, it might
change in future which will make this one obsolete.

We had set the i2c clientdata to &flash->subdev_led[LM3560_LED1]
after call lm3560_subdev_init(flash, LM3560_LED1, "lm3560-led1"),
but the container_of() in lm3560_remove() return the wrong pointer
to flash.(should be container_of(subdev, struct lm3560_flash,
subdev_led[LM3560_LED_MAX-1])
This patch fix to set i2c clientdata to flash so we can get flash
from clientdata directly.

Add the missing unlock before return from function lm3560_set_ctrl()
in the error handling case.

Correct reference of reading values. (rval -> reg_val)
Add the missing unlock before return from function lm3560_get_ctrl()
to avoid deadlock.
Thank you Dan Carpenter & Sakari.

Adds the driver for the LM3560, dual LED Flash The LM3560 has two 1A
constant current driver for high current white LEDs.

It is controlled via an I2C compatible interface(up to 400kHz).

Each flash brightness, torch  brightness and enable/disable can be
controlled independantly, but flash timeout and operation mode are shared.
