[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 1/3] arinc: whitespace and formatting fixes
From: Nathan Studer <nate.studer@xxxxxxxxxxxxxxx>
Remove the excessive amount of trailing whitespace in the
arinc653 scheduler file and add a local variables block.
Suggested-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
