Subject: xen/arm: domain_build: Propagate return code of map_irq_to_domain()
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=5b34e896a3c5fab474e5455d3a74932d46eb756a;p=people%2Froyger%2Fxen.git

xen/arm: domain_build: Propagate return code of map_irq_to_domain()

From map_dt_irq_to_domain() we are assigning a return code of
map_irq_to_domain() to a variable without checking it for an error.
Fix it by propagating the return code directly since this is the last
call.
