From 41a2af93aeebd43daaac397b6662d5822f0742fc Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 31 Jan 2017 11:51:08 +0100 Subject: [PATCH] USB: serial: ark3116: remove redundant interrupt-urb check Remove redundant check of num_interrupt_in which has already been verified in probe (killing a NULL-urb would also have been fine).
