Is this really patch 2/4? I only got patches 2-4, but not patch 1.

Best regards,
Jernej

Sorry I have updated the way I send my patches, so each patch is sent
regarding what is outputted by 'scripts/get_maintainer.pl'

Patch 1 is https://lore.kernel.org/linux-arm-kernel/[email protected]/T/#md5d89721ac1861f31ca5d101ab9561371c35c904

Which has been sent to :
Catalin Marinas / Will Deacon <[email protected]>
And CC to :
[email protected] / [email protected]

I will resend and force this patch to be sent to linux ML / Maintainer too.

Best regards,
Clement
