Subject: RE: [lm-sensors] [PATCH 1/2] Wrong ADT7462_VOLT_COUNT for linux-2.6.30  adt7462 hwmon driver

Hi, Jean, thanks for letting me know.  This is my first time sending a
patch, and I should have sent
it first to Darrick to have him review it before I posted directly to
the group.  He told me how to
rework it properly so that I will do it right next time.

Sorry if this caused any problem for you.

Regards,

Ray Copeland

While the patch looks functionally correct, it is horribly broken in
its format. You sent a HTML mail instead of only plain text. Your
mailer turned the tabs into spaces. And the paths are missing from the
patch header.

Please learn how to send proper patches that kernel maintainers can
apply. Documentation/SubmittingPatches is a good start.
