patch "tools: hv: fcopy: set 'error' in case an unknown operation was" added to char-misc-linus

[gregkh]

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

    tools: hv: fcopy: set 'error' in case an unknown operation was

to my char-misc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-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: tools: hv: fcopy: set 'error' in case an unknown operation was
 requested

'error' variable is left uninitialized in case we see an unknown operation.
As we don't immediately return and proceed to pwrite() we need to set it
to something, HV_E_FAIL sounds good enough.
