------------------------------------------------------
Subject: Fix a potential NULL pointer dereference in write_bulk_callback() in drivers/net/usb/pegasus.c
From: Micah Gruber <micah.gruber@xxxxxxxxx>
This patch fixes a potential null dereference bug where we dereference
pegasus before a null check. This patch simply moves the dereferencing
after the null check.
