The initial effort to correct this issue can be referred here: https://patchwork.kernel.org/patch/107520/ Along with fixing the above stated issue, this patch adds the flexibility option to register notifications from multiple readers to the events received on a mailbox instance. The discussion regarding this can be referred here. http://www.mail-archive.com/linux-omap@vger.kernel.org/msg30671.html Signed-off-by: Hari Kanigeri Signed-off-by: Fernando Guzman Lugo Acked-by: Hiroshi Doyu --- Reading git-diff-tree failed
