Hi Lee, I noticed the DA9061 core support has been added into linux-next, however the commit message was changed from the original title: "mfd: da9061: MFD core support" to add the mistake: "mfd: Add suppfor for DA9061" https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=d3fe0806025cacdab1462d5704e1c98ab9db4564 Can this be fixed please? This patch has not been upstreamed into linux-mainline and is still in linux-next. Regards, Steve

You're right, thanks for pointing that out. Now fixed.
