Guenter Roeck c75f541e12 usb: dwc2: Make "trimming xfer length" a debug message
[ Upstream commit 1a9e38cabd80356ffb98c2c88fec528ea9644fd5 ]

With some USB network adapters, such as DM96xx, the following message
is seen for each maximum size receive packet.

dwc2 ff540000.usb: dwc2_update_urb_state(): trimming xfer length

This happens because the packet size requested by the driver is 1522
bytes, wMaxPacketSize is 64, the dwc2 driver configures the chip to
receive 24*64 = 1536 bytes, and the chip does indeed send more than
1522 bytes of data. Since the event does not indicate an error condition,
the message is just noise. Demote it to debug level.

Fixes: 7359d482eb ("staging: HCD files for the DWC2 driver")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
