The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

<title>ptp: ptp_dte: Convert to platform remove callback returning void</title>

<content type='text'>
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine
implementation. These drivers are not straightforward, as they use
non-standard methods of programming their hardware. They are all converted
to use scaled_ppm_to_ppb to get the parts per billion value that their
logic depends on.

At over 4000 #includes, &lt;linux/platform_device.h&gt; is the 9th most
#included header file in the Linux kernel.  It does not need
&lt;linux/mod_devicetable.h&gt;, so drop that header and explicitly add
&lt;linux/mod_devicetable.h&gt; to source files that need it.

   4146 #include &lt;linux/platform_device.h&gt;

After this patch, there are 225 files that use &lt;linux/mod_devicetable.h&gt;,
for a reduction of around 3900 times that &lt;linux/mod_devicetable.h&gt;
does not have to be read &amp; parsed.

    225 #include &lt;linux/mod_devicetable.h&gt;

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.
