e70140ba0d Get rid of 'remove_new' relic from platform driver struct
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.

ddb8a8a022 EDAC/fsl_ddr: Add support for i.MX9 DDR controller
Add support for the i.MX9 DDR controller, which has different register
offsets and some function changes compared to the existing fsl_ddr
controller. The ECC and error injection functions are almost the same,
so update and reuse the driver for i.MX9. Add a special type 'TYPE_IMX9'
specifically for the i.MX9 controller to distinguish the differences.

3afa157f43 EDAC: Add missing MODULE_DESCRIPTION() macros
With ARCH=arm64

  make allmodconfig && make W=1 C=1

reports:

  WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/edac/layerscape_edac_mod.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes mpc85xx_edac.c and four octeon_edac-*.c files which,
although they did not produce a warning with the arm64 allmodconfig
configuration, may cause this warning with other configurations.

0c7c7ba0c7 EDAC/fsl_ddr: Convert to platform remove callback returning void
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().

fsl_mc_err_remove() is used as callback in two drivers. So these have to
be converted together to the void returning remove callback.

315bada690 EDAC: Check for GHES preference in the chipset-specific EDAC drivers
Call ghes_get_devices() to check whether ghes_edac should be used on the
platform where it is preferred over the corresponding chipset-specific
EDAC driver.

Unlike the existing edac_get_owner() check, the ghes_get_devices() check
works independent to the module_init ordering.
