The crypto mediatek driver has been replaced by the inside-secure
driver now. Remove this driver to avoid having duplicate drivers.

In the init loop, if an error occurs in function 'dma_alloc_coherent',
then goto the err_cleanup section, after run i--,
in the array ring, the struct mtk_ring with index i will not be released,
causing memory leaks

Use devm_platform_ioremap_resource() to simplify the code a bit.
This is detected by coccinelle.

<title>crypto: drivers - Remove dev_err() usage after platform_get_irq()</title>

<id>urn:sha1:514838e920d06f5c2ba56e9656107dfcbbb90219</id>
<content type='text'>
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// &lt;smpl&gt;
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret &lt; 0 \| ret &lt;= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// &lt;/smpl&gt;

While we're here, remove braces on if statements that only have one
statement (manually).

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@

-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)

<title>headers: separate linux/mod_devicetable.h from linux/platform_device.h</title>

<content type='text'>
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.
