As requested by Hans Verkuil: > You accidentally merged the wrong first version of the lm7000 patch series. > > These are the correct second version patches: > > http://patchwork.linuxtv.org/patch/11689/ > http://patchwork.linuxtv.org/patch/11690/ > http://patchwork.linuxtv.org/patch/11691/ > > The second version is much simpler and doesn't require the creation of a whole > new driver.
