Subject: xen/pciback: Don't print scary messages when unsupported by hypervisor.
X-Git-Tag: omap-for-v4.1/fixes-rc1~124^2~11
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74beaf6270f5b08159f1df8208322a24bb2905e6;p=pandora-kernel.git

xen/pciback: Don't print scary messages when unsupported by hypervisor.

We print at the warninig level messages such as:
pciback 0000:90:00.5: MSI-X preparation failed (-38)

which is due to the hypervisor not supporting this sub-hypercall
(which was added in Xen 4.3).

Instead of having scary messages all the time - only have it
when the hypercall is actually supported.
