You forgot to send your Signed-off-by on this patch ;) Anyway, there are other places where EAGAIN may happen. So, the best is to fix it globally. Just applied a fix for it: http://git.linuxtv.org/cgit.cgi/v4l-utils.git/commit/?id=c7c9af17163f282a147ea76f1a3c0e9a0a86e7fa It will retry up to 10 times. This should very likely be enough if the driver doesn't have any bug. Please let me know if this fixes the issue.
