Public bug reported:
[SRU Justification]
[Impact]
This update adds the latest vendor release version on the Exar USB serial
device.
[Fixes]
New features include:
1. Fix for RX fail after wake-up from sleep (S3/S4)
2. Removes unnecessary debug messages
Changelog:
Version 1B, 11/6/2015
Fixed Bug: The conditional logic to support kernel 3.9 was
incorrect(line 396 in xr_usb_serial_common.c).
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
Exar serial devices are typically enumerated as /dev/ttyXRUSB[0-3].
[Regression Potential]
Low. This driver binds to Exar USB Serial devices on the Dell Edge 300x GW.
These updates are being carried in the linux-oem (4.15.y) kernel for more than
2 years without any regressions.
This bug is for tracking purposes only, please don't triage.
