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_*.
