Greg Kroah-Hartman 2037e5d6fb USB-serial updates for 5.15-rc1 
Here are the USB serial updates for 5.15-rc1, including:
 
  - a couple of fixes for cp210x termios error handling
  - retrieval of fw revisions for more cp210x types
  - a switch to octal permissions for all module-parameter definitions
 
 Included are also various clean ups.
 
 All have been in linux-next with no reported issues.

* The 8U232AM has the same API as the sio except for:
* - it can support MUCH higher baudrates; up to:
* o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
* o 230400 at 12MHz
* so .. 8U232AM's baudrate setting codes are different
* - it has a two byte status code.
* - it returns characters every 16ms (the FTDI does it every 40ms)
*
* the bcdDevice value is used to differentiate FT232BM and FT245BM from
* the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
* combinations in both tables.
* FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
* but I don't know if those ever went into mass production. [Ian Abbott]
