3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Stephane Grosjean <s.grosj...@peak-system.com> commit dc50ddcd4c58a5a0226038307d6ef884bec9f8c2 upstream. This patchs fixes a misplaced call to memset() that fills the request buffer with 0. The problem was with sending PCAN_USBPRO_REQ_FCT requests, the content set by the caller was thus lost. With this patch, the memory area is zeroed only when requesting info from the device.
