| * [media] exynos-gsc: Don't use mutex_lock_interruptible() in device release()Sylwester Nawrocki2012-11-26
| | | | | | | | | | | | | | | | | | | | | | | | Use uninterruptible mutex_lock in the release() file op to make sure all resources are properly freed when a process is being terminated. Returning -ERESTARTSYS has no effect for a terminating process and this may cause driver resources not to be released.

* | [media] exynos-gsc: fix variable type in gsc_m2m_device_run()Shaik Ameer Basha2012-10-25
| | | | | | | | | | | | | | | | | | | | In gsc_m2m_device_run(), variable "ret" is accepting signed integer values. But currently it is defined as u32. This patch will modify the type of "ret" variable to "int".
