      USB: pl2303: fix data corruption on termios updates · 623c8263
      Johan Hovold 提交于
      Some PL2303 devices are known to lose bytes if you change serial
      settings even to the same values as before. Avoid this by comparing the
      encoded settings with the previsouly used ones before configuring the
      device.
      
      The common case was fixed by commit bf5e5834 ("pl2303: Fix mode
      switching regression"), but this problem was still possible to trigger,
      for instance, by using the TCSETS2-interface to repeatedly request
      115201 baud, which gets mapped to 115200 and thus always triggers a
      settings update.
