Subject: pciFindStubDriver should return NULL on error
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=12172d18ce7f39c0abf036969e06b7294f07a50f;p=libvirt.git

pciFindStubDriver should return NULL on error

pciFindStubDriver currently returns 0 in one of the error cases.
While it's correct...NULL is more readable.
