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/20220818203928.131059-2-cpe@outsight.tech/T/#md5d89721ac1861f31ca5d101ab9561371c35c904

Which has been sent to :
Catalin Marinas / Will Deacon <will at kernel.org>
And CC to :
linux-arm-kernel at lists.infradead.org / linux-kernel at vger.kernel.org

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

Best regards,
Clement
