Now I see what happened. I have 2 trees from you, the backlight tree (git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight.git#for-backli= ght-next) and the leds-lj tree (git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds.git#for-leds-next) and the former implicitly depends on the latter (and I merge the backlight tree first). You should make that dependency explicit by merging (part of) the latter into the former (or something). --=20 Cheers, Stephen Rothwell --Sig_/GOAK+gnWa=diFn7z7lIQnuw Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmXn3TsACgkQAVBC80lX 0GzRbAf/VnPnRbwDaIyeXQcpSxo0mfy1eM/FQqsOSCrvZU+frg6aVH97QX2b17hy VyKXb6clQHhrFmPnqv5AgrH9KkY39/TliPmYrv0dH3ihV2e3tL8GgYA8KngtqDVv e6WJUlRlwZlfVklxXVA5c+8qFsntcVHrRn1idjmNMNwPP0DeOpxJNpBaskPGshu8 ausC8VpV+qq01D1wCzokw+OrRDvOH1nIpgYe5lksZ/A61E8b9VEKSjj/Q56eh2xX jssDLDyg4eHEqSsEoMA1AeTcdOsqonp2cOPv/XLWONHMw+dpDR8Y9BSSWStnsSqF VBdo6SfJy4VbCbUpQ+G13iPu413asg== =BL6z -----END PGP SIGNATURE----- --Sig_/GOAK+gnWa=diFn7z7lIQnuw--
