This patch series implements clock deregistration in the common clock
framework. Detailed changes are listed at each patch. There is
included an additional patch for the omap3isp driver, required to avoid
regressions.
These patches were rebased on top of 3.13-rc1 and re-retested, are
also available in git repository:
git://linuxtv.org/snawrocki/samsung.git clk/clk-unregister
Changes since v6:
- further fixes of NULL clock handling, minor error log changes.
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_*.
