From 3e748268f391eaf46fe547eb3e51bfec387a63c5 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 23 May 2013 10:43:01 -0300 Subject: [PATCH] [media] coda: do not call v4l2_m2m_job_finish from .job_abort If we just declare the job finished here while the CODA is still running, the call to v4l2_m2m_ctx_release in coda_release, which is supposed to wait for a running job to finish, will return immediately and free memory that the CODA is still using. Just set the 'aborting' flag and let coda_irq_handler deal with it.
