Mon Oct 4 05:57:50 UTC 2021
BugLink: https://bugs.launchpad.net/bugs/1945938
This custom driver was added in Xenial LTS kernel to add support for USB
UART chips:
Product Family: USB UART
Part Numbers:
XR21V1410, XR21V1412, XR21V1414,
XR21B1411, XR21B1420, XR21B1422,
XR21B1424, XR22801, XR22802,
XR22804
In 5.13.x, support for these devices was added to the kernel via.
following patch series:
Link: https://lore.kernel.org/all/20210412095557.1213-1-johan@kernel.org/
Therefore, let's remove this redundant out-of-tree driver.

-Exar USB Serial Driver
-======================
-Version 1A, 1/9/2015
-
-This driver will work with any USB UART function in these Exar devices:
- XR21V1410/1412/1414
- XR21B1411
- XR21B1420/1422/1424
- XR22801/802/804
-
-The source code has been tested on various Linux kernels from 3.6.x to 3.17.x.
-This may also work with newer kernels as well.
-
-
-Installation
-------------
-
-* Compile and install the common usb serial driver module
-
- # make
- # insmod ./xr_usb_serial_common.ko
-
-
-* Plug the device into the USB host. You should see up to four devices created,
- typically /dev/ttyXRUSB[0-3].
-
-
-Tips for Debugging
-------------------
-
-* Check that the USB UART is detected by the system
-
- # lsusb
-
-* Check that the CDC-ACM driver was not installed for the Exar USB UART
-
- # ls /dev/tty*
-
- To remove the CDC-ACM driver and install the driver:
-
- # rmmod cdc-acm
- # modprobe -r usbserial
- # modprobe usbserial
- # insmod ./xr_usb_serial_common.ko
-
-
-Technical Support
------------------
-Send any technical questions/issues to uarttechsupport at exar.com.
