When the current context is running, 1] If release() or streamoff() is called on the current context, it waits until the job is aborted or finished. 2] If the job is finished, driver will call the v4l2_m2m_job_finish(). 3] If the job is aborted inside device_run callback, then driver has to inform the v4l2 mem2mem framework about the same by calling v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR. The current code doesn't call v4l2_m2m_job_finish() in the case, where the job is aborted from the device_run callback. This scenerio is producing a hang as the other queued contexts are not getting scheduled. By adding the ABORT state, driver can understand the current job is aborted and not finished. By checking this flag, driver can call v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR.
