led_set_brightness() involves scheduling a workqueue. As here the led's
brightness setting is done in context of the trigger's workqueue this is
unjustified overhead and it's more sensible to use
led_set_brightness_sync().

ttyname is allocated before the mutex is taken, so it must not be
unlocked in the error path.

Pull LED updates from Pavel Machek:
 "Besides the usual fixes and new drivers, we are changing CLASS_FLASH
  to return success to make it easier to work with V4L2 stuff disabled,
  and we are getting rid of enum that should have been plain integer
  long time ago. I'm slightly nervous about potential warnings, but it
  needed to be fixed at some point"

Pull tty/serial driver updates from Greg KH:
 "Here is the big set of tty/serial driver changes for 5.12-rc1.

  Nothing huge, just lots of good cleanups and additions:

   - n_tty line discipline cleanups

   - vt core cleanups and reworks to make the code more "modern"

   - stm32 driver additions

   - tty led support added to the tty core and led layer

   - minor serial driver fixups and additions

  All of these have been in linux-next for a while with no reported
  issues"

In the line like

	u32 bar = ...;
	u8 foo = (u8)(bar >> 8) & 0xff;

is no need to have neither explicit casting nor ' & 0xff' part.
Get rid of them.

The OF is not used in the driver, thus the OF headers are not needed,
but mod_devicetable.h is missed.

Since GPIO is optional the API is NULL aware and will check descriptor anyway.

The priv->dev is effectively the same as &priv->client->dev.
So, drop the latter for the former.

Switch to the new style i2c-driver probe_new probe function.
Note we do not have any old style board files using this but
user still has a possibility to instantiate device from sysfs.
