This patch series implements clock deregistration in the common clock
framework. This is required for proper support of clock suppliers as
loadable modules. Previous version of this series can be found at [1].
Comparing to v4 only a stray struct module forward declaration has been
removed from patch 3/5. My apologies for spamming.
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_*.
