Colin Ian King d42282db6c iio: adc: ina2xx: add in early -EINVAL returns in case statements
Static analysis with CoverityScan is throwing warnings that specific
case statements are missing breaks.  Rather than adding breaks, add
return -EINVAL to the specific case statements to clarify the
error return paths. Fix also saves 50 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  21418	   4936	    128	  26482	   6772	drivers/iio/adc/ina2xx-adc.o

After:
  dec	    hex	filename
  21370	   4936	    128	  26434	   6742	drivers/iio/adc/ina2xx-adc.o

(gcc 8.2, x86-64)

Detected by CoverityScan, CID#1462408 ("Missing break in switch")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
