[PATCH 0/5] Remove MODULE_ALIAS from all mcb client drivers

[PATCH 0/5] Remove MODULE_ALIAS from all mcb client drivers

[Javier Rodriguez]

The first patches I sent for fixing the autoload problem encountered
on mcb device drivers were 2. The first was focused on updating the
modpost process for letting kbuild to access to the data within
MODULE_DEVICE_TABLE and the second one for removing the MODULE_ALIAS
on all mcb client drivers.

They were rejected and Andy suggested me to split the second patch
in a per-driver basis instead of sending all drivers' changes in a
single patch once the first patch was merged.

You can find the messages here:

https://lore.kernel.org/all/CAHp75VfhM5GuYY1qUKgBhePDo4oe5k3K1ZDTPbYJNr5NtjVVfQ@mail.gmail.com/

The first patch is already merged on Linus's Git repository for 6.19-rc4

commit 1f4ea4838b13 ("mcb: Add missing modpost build support")

So now I am sending this patch series for removing MODULE_ALIAS
on all mcb client drivers as it is no longer required.

[PATCH 1/5] gpio: gpio-menz127: drop unneeded MODULE_ALIAS

[Javier Rodriguez]

From: Jose Javier Rodriguez Barbarin <dev-josejavier.rodriguez@duagon.com>

The MODULE_ALIAS() is redundant since the module alias is now
automatically generated from the MODULE_DEVICE_TABLE().

Remove the explicit alias.

No functional change intended.

This is not compatible with the Open Source workflow. Please, make sure there
is no footer in the next version.

Also, you missed a cover letter. Or send the patches separately as I don't see
now any evidence of the cross patch dependency.

This is a bit embarrasing. I forgot to configure git to use tu proper email account.

Yes, I decided to send the patches in a way that was not the best. So I'm going to
send the patches separately for each subsystem.

From the patch description I'm not seeing how this is a fix?
Seems like cleanup of unnecessary code given what you have written above.

Unless the generated alias is not "mcb:16z069", and it is unlikely that
it is. That means it is not really redundant.
