[ Upstream commit ab3df79782e7d8a27a58576c9b4e8c6c4879ad79 ]
On an IRQ handler we should not return normal error codes as 'irqreturn_t'
is expected.
Not necessary to apply to stable as the original check cannot fail and
as such the bug cannot actually occur.

commit a71266e454b5df10d019b06f5ebacd579f76be28 upstream.
This is to silence a new Smatch warning:
drivers/iio/imu/adis16400.c:492 adis16400_initial_setup()
warn: sscanf doesn't return error codes
If the condition "if (st->variant->flags & ADIS16400_HAS_SLOW_MODE) {"
is false then we return 1 instead of returning 0 and probe will fail.

Final part of the re-organization. Move the `adis16400.h` into
`adis16400.c` since it no longer needs to be shared among other files.

This change does a simple 1-to-1 rename of the adis16400_core.c file. Now
that the `adis16400_buffer.c` file was removed, everything can be moved
into a single driver file.
But first, this rename.
