Please see my comments to patch 20. I guess this series break support
for the digital-only boards below (where .has_analog is not set):
[AU0828_BOARD_HAUPPAUGE_HVR950Q_MXL] = {
.name = "Hauppauge HVR950Q rev xxF8",
.tuner_type = TUNER_XC5000,
.tuner_addr = 0x61,
.i2c_clk_divider = AU0828_I2C_CLK_250KHZ,
},
[AU0828_BOARD_DVICO_FUSIONHDTV7] = {
.name = "DViCO FusionHDTV USB",
.tuner_type = TUNER_XC5000,
.tuner_addr = 0x61,
.i2c_clk_divider = AU0828_I2C_CLK_250KHZ,
},
[AU0828_BOARD_HAUPPAUGE_WOODBURY] = {
.name = "Hauppauge Woodbury",
.tuner_type = TUNER_NXP_TDA18271,
.tuner_addr = 0x60,
.i2c_clk_divider = AU0828_I2C_CLK_250KHZ,
},
None of this boards have V4L2. So, only the DVB part of the driver
should be enabled. Well, the DVB core won't be creating a tuner
subdev. So, calling au0828_enable_source() (and disable source) would
return -ENODEV, causing the driver to fail.

It is in a way better shape, but there are still several things I
noticed :)
Please see my per-patch review.

You need at least address pure DVB boards at patch 20 and
add there a FIXME for the composite/svideo connector pending
issue.

Please send documentation at the same series. Nobody wants to see the
documentation warnings when checking at the main media development
branch or at -next. Also, it helps to better understand the changes.
