Subject: [PATCH 0/9] USB: serial: generic driver fixes and bulk buffer feature

Hi,

Here are a few of fixes to the generic driver as well as a new feature that
lets drivers determine the size of the bulk buffers more easily. It turns out
that increasing the out-buffer sizes for cp210x and pl2303 have a significant
effect on throughput.

Thanks,
Johan

Johan Hovold (9):
  USB: serial: allow drivers to define bulk buffer sizes
  USB: cp210x: increase the bulk-out buffer size to 256 byte
  USB: cp210x: increase bulk-in buffer size to 256 byte
  USB: pl2303: increase the bulk-out buffer size to 256 byte
  USB: pl2303: increase bulk-in buffer size to 256 byte
  USB: serial: fix generic chars_in_buffer
  USB: serial: fix missing locking on fifo in write callback
  USB: serial: clear fifo on close
  USB: serial: refactor generic close
