Subject: [media] exynos4-is: Free FIMC-IS CPU memory only when allocated Author: Sylwester Nawrocki <[email protected]> Date: Thu May 8 14:35:15 2014 -0300 Ensure dma_free_coherent() is not called with incorrect arguments and only when the memory was actually allocated. This will prevent possible crashes on error paths of the top level media device driver, when fimc-is device gets unregistered and its driver detached.
