NACK: [SRU] [F/G/Unstable/OEM-5.6] [PATCH 0/3] Fix broken MSI interrupt after HDA controller was suspended

[Kai-Heng Feng]

The series is broken because of the following error:

msmtp: TLS handshake failed: The TLS connection was non-properly terminated.
msmtp: could not send mail (account default from /home/khfeng/.msmtprc)
Died at /usr/lib/git-core/git-send-email line 1436.

Please refer to the [RESEND] one instead.
