Hi Pavel, Lee,

I am sending version 3 of Turris Omnia's LED controller updates.
Please read the summary (changes from version 2):
- added patch 1, which drops unnecessary mutex locking
- added patch 2, which changes SMBUS calls to regular I2C transfers
- added patch 3, changing sprintf() to dedicated sysfs_emit()
- patch 4 replaces patch 1 from v2, which changed max_brightness to 1.
  Instead, we make set_brightness() more effective by avoiding
  unnecessary I2C transactions (for example if brightness is being
  changed between 0 and 255, we do not send the color changing I2C
  command, only the enabling/disabling command)
- patch 5 is updated patch 3 from v2, which adds support for enabling
  HW blinking mode on the LEDs
- patch 6 adds support for enabling/disabling HW gamma correction of
  the RGB LEDs. Gamma correction is supported by newer MCU firmware
  versions
