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

    staging: r8188eu: Calling rtw_get_stainfo() with a NULL sta_addr will

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: r8188eu: Calling rtw_get_stainfo() with a NULL sta_addr will
 return NULL

This makes the follow-on check for psta != NULL pointless and makes
the whole exercise rather pointless. This is another case of why
blindly zero-initializing variables when they are declared is bad.
