Buffer wasn't of a valid size to allow the timestamp, and correct padding.
This patchset also moves the buffer off the stack, and onto the heap.

This is not implemented and doesn't really make sense because IIO
proximity is unit-less.

Remove IIO_CHAN_INFO_SCALE from info_mask because so that the _scale
sysfs entry won't appear. This fixes userspace tools like generic_buffer
which abort when reads returns an error.

Apply the correct mask to enable all available humidity integration
times.  Currently, the driver defaults to 6500 and all is okay with that.
However, if 3850 is selected we get a stuck bit and can't change back
to 6500 or select 2500.  (Verified with HDC1008)

The bmp280 driver also supports BMP180 which has a different chip id
with BMP280.  The probe routine verifies that the device reports the
correct chip id but the error message is confusing as if BMP280's chip
id is always expected.

mite_setup() after allocating and initializing the mite device
with mite_attach().

Move the mite_setup() call into mite_attach() to simplify the

exported functions.

An allocated mite_channel will have its 'ring' member initialized
to point to the mite_ring that will be used for DMA. A non-allocated
mite_channel will have a 'ring' member set to NULL, either by a
channel release or due to the initial kzalloc of the 'mite' struct.

Refactor the code to use the mite_chan->ring to detect in a channel
is allocated and remove the unnecessary member.
