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.
