Date: Wed, 29 Oct 2014 20:03:54 +0400 From: Andrey Utkin <andrey.krieger.utkin@...il.com> To: linux-kernel@...r.kernel.org, linux-media@...r.kernel.org, devel@...verdev.osuosl.org Cc: ismael.luceno@...p.bluecherry.net, m.chehab@...sung.com, hverkuil@...all.nl, Andrey Utkin <andrey.krieger.utkin@...il.com> Subject: [PATCH 4/4] [media] solo6x10: don't turn off/on encoder interrupt in processing loop The used approach actually cannot prevent new encoder interrupt to appear, because interrupt handler can execute in different thread, and in current implementation there is still race condition regarding this. Also from practice the code with this change seems to work as stable as before.
