[PATCH 1/5] staging: r8188eu: remove tmp variable in update_recvframe_attrib_88e

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

 



Remove an unnecessary temporary variable in update_recvframe_attrib_88e.
We can use the prxstat pointer directly to parse the input data. There's
no need to store a local copy in "report".
