X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33fdfa97f2b3aab698ef849ec50dcc5102017f0a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git 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.
