From bc4b1f486fe69b86769e07c8edce472327a8462b Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Sun, 15 Feb 2015 11:57:53 +0700 Subject: Revert "USB: serial: make bulk_out_size a lower limit" This reverts commit 5083fd7bdfe6760577235a724cf6dccae13652c2. A bulk-out size smaller than the end-point size is indeed valid. The offending commit broke the usb-debug driver for EHCI debug devices, which use 8-byte buffers.
