This is a note to let you know that I've just added the patch titled
debugfs: debugfs_create_file_size(): use IS_ERR to check for error
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

debugfs_create_file() returns encoded error so use IS_ERR for checking
return value.
