[PATCH 11/14] staging: android: ion: Allow heap name to be null

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The heap name can be used for debugging but otherwise does not seem
to be required and no other part of the code will fail if left NULL
except here. We can make it required and check for it at some point,
for now lets just prevent this from causing a NULL pointer exception.
