Kinsey,
Thanks for the feedback! I added the git config as recommended.
Response to your comment is inline below.

Hey Rick,
This looks good for the most part and thanks for the contribution.
For future patches, please make sure you specify the repository in
your subject line if the patch isn't for the RTEMS repository. This
can be configured to occur automatically in your local per-repo git
configuration using this:
git config format.subjectprefix "PATCH rtems-libbsd"
This should actually be referenced in the git docs for this project,
but it appears that there's a mistake in the markup that I'm about to
go fix.
Just one comment inline below:

This fixes an issue where the card present signal doesn't stabilize
quickly and indicates present when no card is inserted in a removable
slot.

What is "CD"? Should this be "SD"?
CD is the "Card Detect" signal line from the SD card socket. In this
case it may be better to spell out to avoid confusion.
