[PATCH v2 0/4] Prepare consoles, add fb flush and Solomon SSD1307 OLED controller support

[Bastian Stender]

Changes since last version:

console: replace set_active by open/close
  - use a counter rather than flags
  - inrease counter independent of the presence of the cdev->open() hook

console: expose consoles in devfs
  - test for presence before using flush hook

video: add support for Solomon SSD1307 OLED controller family
  - remove pwm dependency and SSD1307 compatibility
  - use tabs and spaces consistently
  - remove unnecessary 'struct ssd1307fb_par'
  - remove unnecessary xzalloc check
  - bail out if any of the *required* device tree properties are missing
  - replace errno on gpio failure with error string
  - remove obsolete printk include
