This and patch 4 look good as is but they don't apply against for-5.7 due to context changes in -next, unfortunately everyone seems to have decided that now is the time to start working on this driver which makes combinations of new work and fixes awkward. I'm going to apply these for 5.8 but it'd be good if you could send versions based on for-5.7 as well so I can apply there - I can sort out the conflicts with 5.8. --/0U0QBNx7JIUZLHm Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl6+xloACgkQJNaLcl1U h9ABrwf/WQm+mOxb45Hxt0ho5+NLAIHIGJtDEbVnzaKIAHrJ76Kzbfpw1etZeWdL NFMGaUa7GJED/7kuBofBOtVn34ZIuNrtS0ljxoxka2Ajcz3nmXxshzzgC8PkiDMG sCDtGqBikWu9Yy/GqD7y5BfrZ279aadvlln4JTM0PCAILyQ39kps+aliMjXeHsdc UrSJjBUuMePJ9LDjKQ8vzzTmQkrxQ5rKYL7vvIFA6shq3Yn21unkO0UqFfNVRgSQ jdwUSiSYndO+lwk2aHH2jHmrwpZMsdiDGCtNX9VAn6D2lYdYmhNKmWPUF0BqeIp9 5Zvi4BlaUwxZS+41vq5pOJaIEhH4BA== =rfwh -----END PGP SIGNATURE----- --/0U0QBNx7JIUZLHm--
