------------------

From: Marc Kleine-Budde <mkl@pengutronix.de>

commit 20fb4eb96fb0350d28fc4d7cbfd5506711079592 upstream.

This patch fixes a memory leak in pcan_usb_pro_init(). In patch

    f14e224 net: can: peak_usb: Do not do dma on the stack

the struct pcan_usb_pro_fwinfo *fi and struct pcan_usb_pro_blinfo *bi were
converted from stack to dynamic allocation va kmalloc(). However the
corresponding kfree() was not introduced.

This patch adds the missing kfree().
