Subject: hw/sensor/tmp105: Pass 'oneshot' argument to tmp105_alarm_update()
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=0339fa791046288311501e06361f4d3f7e7270df;p=qemu-xen.git

hw/sensor/tmp105: Pass 'oneshot' argument to tmp105_alarm_update()

The next commit will clear the ONE_SHOT bit in the WRITE
path (to keep the READ path trivial). As a preliminary step,
pass the 'oneshot' value as argument to tmp105_alarm_update().
No logical change intended.
