From: Hans Verkuil Date: Fri, 2 Mar 2012 16:02:11 +0000 (-0300) Subject: [media] ivtv: simplify how the decoder controls are set up X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eb2ba855470797b20dced364f5897cc949e7ade6;p=linux-beck.git [media] ivtv: simplify how the decoder controls are set up The code was unnecessarily complex, introducing a hdl_out handler that was not needed. Instead just add the controls to the cxhdl.hdl handler directly.
