Please make clear that this is the report the original patch wanted to fix. As nobody closed it yet, it does not need to be reopened. You can reference the LKML thread directly though. https://lkml.org/lkml/2013/2/18/353 > Signed-off-by: Takahisa Tanaka <mc74h...@gmail.com> > --- > drivers/watchdog/sp5100_tco.c | 140 > ++++-------------------------------------- > drivers/watchdog/sp5100_tco.h | 2 +- > 2 files changed, 14 insertions(+), 128 deletions(-) […] To address Greg’s comment, your patch first has to land in Linus’ master branch and only then it can be backported/applied to the stable series. This will be done automatically if you just add CC: sta...@vger.kernel.org to the end of the commit message. Thanks, Paul
