Hi Narcisa,

Is this enum then used in a type declaration?

BTW - I can see Jonathan is following right along and sweeping these up,
but for future reference, this patch depended on a previous patch sent hours
earlier, that was not yet in staging-testing.  When this happens, one option
is to give a note below the --- (as you would for version comments) stating the
dependency.  This way someone reviewing the patch doesn't simply reject
it as not applying to my tree.

  Hi,

  Do you mean whether there are any type declarations where I could
  now replace the type with the enum type ? If so, I searched for 
  these type of situations, but didn't find any. If I missed one of
  these cases, please let me know and I'll send a new patch.

  Thank you for the note about the patch dependencies. I was just about
  to ask about this, cause I realized there might be a problem.
  I'll keep in mind to make a note next time.

Typically the constant would be stored in something, compared to
something, etc.  Are these constants not used at all?

  Yes, they are used, they are stored. I thought she was asking
  if I encountered any situations like in adc/ad7280a.h file
  where you could define an enum for conversion averaging
  macros and replace the 'unsigned int' field in the 
  ad7280_platform_data with the enum type.

If they are stored in something, I guess you could change the type of that
thing?

  The scan indexes(si) are given to macros such as:
  
  #define ADIS_ACCEL_CHAN(mod, addr, si, info_sep, info_all, bits) \
    ADIS_MOD_CHAN(IIO_ACCEL, mod, addr, si, info_sep, info_all, bits)
  
  (defined in the linux/iio/imu/adis.h header). 
  which are used to initialize the adis162xx_channels[].

  Since they are used like this, I don't see anything I can
  replace/improve here.
  Am I missing something? 

  Narcisa.
