Merge tag 'gpmc-omap-for-v4.9' of https://github.com/rogerq/linux into next/drivers

Merge "OMAP-GPMC: driver updates for v4.9" from Roger Quadros:

* Fix potential build failure if CONFIG_OMAP_GPMC is disabled while
  OMAP_NAND driver is enabled
* Trivial fixes which fix build warnings and code check tool warnings
  (Coccinelle)
* Use devm_gpiochip_add_data()

* tag 'gpmc-omap-for-v4.9' of https://github.com/rogerq/linux:
  memory: omap-gpmc: make gpmc_clk_ticks_to_ns() static
  memory: omap-gpmc: Fix build with CONFIG_OMAP_GPMC disabled
  memory: omap-gpmc: use devm_gpiochip_add_data()
  memory: omap-gpmc: Delete an unnecessary check before the function call "gpiochip_free_own_desc"
