Re: [Outreachy kernel] [PATCH v3 4/4] staging: sm750fb: Remove typedefs

[Julia Lawall]

Greg requested that typedef removing patches adjust only one patch at a
time.

The names of the types typically need to be adjusted as compared to what
is in the typedef.  In your cases, the type names begin with _ and end
with _t.  Beginning with _ means that something is sort of internal,
rarely used etc.  That made sense when there was a typedef, but since you
are removing that, the _ at the front should go too.  Likewise, _t is an
extension that indicates a typedef, but you don't have that any more, so
the _t should be dropped too.

Finally, the log message talks about structures, but the changes involve
one structure and one enum.  The log message should describe everything
that has changed.
