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. Fixes: 5083fd7bdfe6 ("USB: serial: make bulk_out_size a lower limit") Reported-by: "Li, Elvin" <elvin.li@intel.com> Cc: stable <stable@vger.kernel.org> # v3.15 Signed-off-by: Johan Hovold <johan@kernel.org>
