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@xxxxxxxxxxxxx/T/#md5d89721ac1861f31ca5d101ab9561371c35c904
Which has been sent to :
Catalin Marinas / Will Deacon <will@xxxxxxxxxx>
And CC to :
linux-arm-kernel@xxxxxxxxxxxxxxxxxxx / linux-kernel@xxxxxxxxxxxxxxx
I will resend and force this patch to be sent to linux ML / Maintainer too.
Best regards,
Clement
