Subject: [PATCH] iio: adc: Add missing MODULE_DEVICE_TABLE

From: Chunyan Zhang <[email protected]>

MODULE_DEVICE_TABLE is used to extract the device information out of the
driver and builds a table when being compiled. If using this macro,
kernel can find the driver if available when the device is plugged in,
and then loads that driver and initializes the device.

Applied to the togreg branch of iio.git and pushed out as testing to see
if 0-day can find anything we missed.

Thanks,
