[PATCH 4.9 069/118] libertas_tf: dont set URB_ZERO_PACKET on IN USB transfer

From: Greg Kroah-Hartman
Date: Fri Mar 22 2019 - 07:43:04 EST

4.9-stable review patch. If anyone has any objections, please let me know.


From: Lubomir Rintel <lkundrak@xxxxx>

commit 607076a904c435f2677fadaadd4af546279db68b upstream.

It doesn't make sense and the USB core warns on each submit of such
URB, easily flooding the message buffer with tracebacks.

Analogous issue was fixed in regular libertas driver in commit 6528d8804780
("libertas: don't set URB_ZERO_PACKET on IN USB transfer").
