[PATCH v2] staging: vt6655: replace camel case by snake case
Posted by Pavan Bobba 2 years, 3 months ago 
1.Conversion of formal argument names from camel case to snake case for below functions:
      a.SROMvReadAllContents
      b.SROMvReadEtherAddress

2.Conversion of local variable names from camel case to snake case in function SROMvReadEtherAddress

When you list the different things you are doing, that usually means you
want multiple patches.  Would you want to review something that mixed
something like this together?

Also, please read the kernel documentation for how to write a good
changelog, and subject, this subject is identical to the one that you
were told to change and you agreed to :(

You also forgot to actually cc: the maintainer that could take this
patch :(

You now have an alignment issue, right?  Did you run this through
checkpatch?

Maybe the W_ should also be dropped?

Here you could add some spaces to get the - EEPROM to line up with the
rest.  Likewise later.
