> Will it be better, if dvb_pll_devcount is decremented in dvb_pll_release(), instead of removing module params? But you cannot know deterministically which device corrensponds to what "id" (when you have multiple dvb_pll devices), since "id" is dependent on the history of register and unregister of dvb_pll devices. So I wonder about the benefit / practical usecase of "id" parameter. -- Akihiro
