Subject: qdev: Add a DEV_NVECTORS_UNSPECIFIED enum for unspecified nr of MSI vectors
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~8514
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=75422b0d38029d2e098309da4dd7199dc7b2d2a9;p=sdk%2Femulator%2Fqemu.git

qdev: Add a DEV_NVECTORS_UNSPECIFIED enum for unspecified nr of MSI vectors

net.c used a constant to signify no MSI vectors were specified. Extend
that to all qdev devices.
