This patch is reverted by [2], so please upstream it via the platform maintainers. regards, Marc [1] https://lore.kernel.org/all/20230423172528.1398158-2-dario.binacchi@ama= rulasolutions.com [2] https://lore.kernel.org/all/20230517181950.1106697-1-mkl@pengutronix.de --=20 Pengutronix e.K. | Marc Kleine-Budde | Embedded Linux | https://www.pengutronix.de | Vertretung N=C3=BCrnberg | Phone: +49-5121-206917-129 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-9 | --dfmegg2limou4kpi Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEDs2BvajyNKlf9TJQvlAcSiqKBOgFAmRlHQYACgkQvlAcSiqK BOjyEQf/aWrP70IM+PLkOxyyzdSFXZNts5KYn9gvAzbtWKcHJv25ppouGeg4aTxz gye9TQwUmW8hfzy6geTXaLuQmefpCUvBg+yESzHFHL6jLXM2gwzkhenwdTDeSow5 JoEAOmQR9gl5W+vK8o9MtMmOsoQ574crp2UV3Xn4tBP9xDBqVUxXla4RQpTsx6Db OJMnWAYl6mheQsIkPwfxuafXkVvu2yH1ah89dPko0oQeCZFMOpnLorKUG9SAzOEV LUKzryIlvWpklji2KpLf1RTqrUUTEcMmPaBKEM99QhR/51yr3pLPgKHTMJwpbvJz abfH52OdzM13H/oBWKxLuHHzseSgeg== =O32s -----END PGP SIGNATURE----- --dfmegg2limou4kpi-- --===============4441192359456828525== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============4441192359456828525==--
