Daniel Lenski c4a9967e4d Bluetooth: btusb: Add a new QCA_ROME device (0cf3:e500) 
[ Upstream commit 0324d19cb99804d99e42c990b8b1e191575a091b ]

This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a
QCA_ROME device.  It appears to be functionally identical to another device
ID, also from a QCA9377 board, which was previously marked as QCA_ROME in
0a03f98b98
("Bluetooth: Add a new 04ca:3015 QCA_ROME device").

Without this patch, the WiFi side of the QCA9377 board is slow or unusable
when the Bluetooth side is in use.

See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing
this issue for this device ID.

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.
