Giant on serial devices in USB2?

[Ed Schouten]

Hello HPS, others,

I was just running a grep on the USB2 code and saw the following:

$ grep -r Giant sys/dev/usb2/serial | wc -l
      70

WHat's the exact reason USB2 still uses Giant on TTY related drivers?
Couldn't it just use the per-TTY mutex? If not, maybe it should create a
custom system-wide mutex, instead of using Giant?

Yours,
