Subject: pvrdma: release device resources in case of an error
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=cce648613bc802be1b894227f7fd94d88476ea07;p=qmiga%2Fqemu.git

pvrdma: release device resources in case of an error

If during pvrdma device initialisation an error occurs,
pvrdma_realize() does not release memory resources, leading
to memory leakage.
