[RFC PATCH 3/3] CXL/doe: Use devm_xa_init()

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

 



From: Ira Weiny <ira.weiny@xxxxxxxxx>

The DOE mailboxes are all allocated with device managed calls.
Therefore, the XArray can go away when the device goes away.

Use devm_xa_init() and remove the callback needed for xa_destroy().
