[PATCH v7 0/5] clk: clock deregistration support

[Sylwester Nawrocki <s.nawrocki@samsung.com>]

This patch series implements clock deregistration in the common clock
framework. Detailed changes are listed at each patch. I have included
an additional patch in this series for the omap3isp driver, required 
to avoid regressions.

Changes since v5:
 - fixed NULL clock handling in __clk_get(), __clk_put (patch 5/5).

Changes since v4:
 - removed stray struct module forward declaration in patch 3/5.

Changes since v3:
 - replaced WARN_ON() with WARN_ON_ONCE() in clk_nodrv_disable_unprepare()
   callback.

Changes since v2:
 - reordered the patches so the race condition is fixed before it can
   actually cause any issues,
 - fixed handling of NULL clock pointers in __clk_get(), __clk_put(),
 - added patch adding actual asignment of clk->owner; more details are
   discussed in that specific patch.

Changes since v1:
 - moved of_clk_{lock, unlock}, __of_clk_get_from_provider() function
   declaractions to a local header,
 - renamed clk_dummy_* to clk_nodrv_*.

  clk: Provide not locked variant of of_clk_get_from_provider()
  clkdev: Fix race condition in clock lookup from device tree
  clk: Add common __clk_get(), __clk_put() implementations
  clk: Implement clk_unregister()
