MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit b790f210fe8423eff881b2a8a93ba5dbc45534d0 upstream. The sleep function was updated to put the serial port to sleep only when necessary. This appears to resolve the errant behavior of the driver as described in Kernel Bug 61961 – "My Exar Corp. XR17C/D152 Dual PCI UART modem does not work with 3.8.0".
