[PATCH 3.4 27/35] vmxnet3: fix building without CONFIG_PCI_MSI

From: Greg Kroah-Hartman
Date: Thu Mar 20 2014 - 20:16:00 EST


3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

commit 0a8d8c446b5429d15ff2d48f46e00d8a08552303 upstream.

Since commit d25f06ea466e "vmxnet3: fix netpoll race condition",
the vmxnet3 driver fails to build when CONFIG_PCI_MSI is disabled,
because it unconditionally references the vmxnet3_msix_rx()
function.

To fix this, use the same #ifdef in the caller that exists around
the function definition.
