Mauro Carvalho Chehab bfc3d57ff7 V4L/DVB: tda18271: Add some hint about what tda18217 reg ID returned
Instead of doing:

[   82.581639] tda18271 4-0060: creating new instance
[   82.588411] Unknown device detected @ 4-0060, device not supported.
[   82.594695] tda18271_attach: [4-0060|M] error -22 on line 1272
[   82.600530] tda18271 4-0060: destroying instance

Print:
[  468.740392] Unknown device (0) detected @ 4-0060, device not supported.

for the error message, to help detecting what's going wrong with the
device.

This helps to detect when the driver is using the wrong I2C bus (or have
the i2g gate switch pointing to the wrong place), on devices like cx231xx
that just return 0 on reads to a non-existent i2c device.
