[patch 24/24] Synaptics - fix setting packet size on passthrough port

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


From: Sergey Vlasov <[email protected]>

Input: synaptics - fix setting packet size on passthrough port.

Synaptics driver used child->type to select either 3-byte or 4-byte
packet size for the pass-through port; this gives wrong results for
the newer protocols. Change the check to use child->pktsize instead.
