I'll queue it for 3.12. We actually have similar patch for the exynos4-is fimc-is-i2c driver.

[PATCH] [media] exynos-gsc: fix s2r functionality
From: Prathyush K When gsc is in runtime suspended state, there is no need to call m2m_suspend during suspend and similarily, there is no need to call m2m_resume during resume if already in runtime suspended state. This patch adds the necessary conditions to achieve this.
