Subject: [PATCH AUTOSEL for 4.9 197/293] net: cdc_mbim: apply "NDP to end"
 quirk to HP lt4132

From: Tore Anderson <tore@....no>

[ Upstream commit a68491f895a937778bb25b0795830797239de31f ]

The HP lt4132 LTE/HSPA+ 4G Module (03f0:a31d) is a rebranded Huawei
ME906s-158 device. It, like the ME906s-158, requires the "NDP to end"
quirk for correct operation.
