Patch Broken driver cx23885 mygica x8507

Hi all

I found that this is the patch that makes no sound and deformation image on mygica x8507:

http://git.kernellabs.com/?p=stoth/cx23885-hvr1850-fixups.git;a=commit;h=e187d0d51bcd0659eeac1d608284644ec8404239

I will try to find that lines are responsible.

Please refer to the patch mentioned above.

lines that leave without sound to the card are these:

@@ -1086,6 +1232,23 @@ static int set_input(struct i2c_client *client, enum cx25840_video_input vid_inp

                cx25840_write4(client, 0x8d0, 0x1f063870);
        }

->+ cx25840_and_or(client, 0x803, ~0x10, 0x00);
->+ }
+ }
+

        return 0;

}

Without these lines, have sound.

And the following line produces a vertical green bar on the right and the image is a bit narrow (maybe taken as an image of 702 pixel). If I cancel that line, the image is colored with alternating bars and color distorted.

@@ -631,6 +654,37 @@ static void cx23885_initialize(struct i2c_client *client)

+ */
->+ cx25840_write4(client, 0x404, 0x0010253e);

With kernel 3.0, 3.1 and 3.2 the card worked fine.

Thanks,

Alfredo
