It's fine if you break this line into two lines.
arm: omap3: beagle: Ensure msecure is mux'd to be able to set the RTC.
"Msecure" signal provides for protection of the RTC register in
TPS65950 be
disabling that function via a control signal from the OMAP3530. So ensure
msecure is mux'd to be able to set the RTC.

Tested with a BeagleBoard C4.
Fixes bug [YOCTO #767]
I think it's best to put your comment in the top line.
And we don't want the bug tracking information directly
in the kernel commits, it just ends up cluttering things.

It's fine to include this in the 0/N email, but not in
the commit message itself.
