| | | | | | | | ion_client_create now does a lookup, so this need not also be done from ion_open Change-Id: Icb101bbf514bf2e40b4b5d9b320130bf185349aa Signed-off-by: Rebecca Schultz Zavin <rebecca@android.com>

* gpu: ion: Remove incorrect error messageRebecca Schultz Zavin2011-06-301-2/+0
| | | | | | | | | | The function name is wrong here, and this function may sometimes be called to see if a value passed from userspace is an ion handle. Since it's not really an error when it fails, remove the log message. Change-Id: I7bee0e7ffb72b4c4768774a3586f97e306700c21 Signed-off-by: Rebecca Schultz Zavin <rebecca@android.com>
