patch "staging: nvec: remove managed resource from PS2 driver" added to staging-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    staging: nvec: remove managed resource from PS2 driver

to my staging git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-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.

Subject: staging: nvec: remove managed resource from PS2 driver

This basicly reverts commit e534f3e9 (staging:nvec: Introduce the use of
the managed version of kzalloc). Serio struct should never by managed
because it is refcounted. Doing so will lead to a double free oops on module
remove.
