No, you're right. It's merely a clean up and slight optimisation as no
chars_in_buffer needs the disconnect mutex after the other changes. Not
sure why it wouldn't apply, though.
I was a bit sloppy when I gave the commit refs above -- it should have
been
0693196^..b16634a
More specifically:
4746b6c USB: serial: clean up chars_in_buffer
This one is not strictly necessary, but should apply to v3.9.
ff93b19 USB: ti_usb_3410_5052: fix chars_in_buffer overhead
This should not be applied to v3.9 as the problem it fixes
wasn't introduced until v3.10-rc1.
It seems you had to add two other patches to get this one to
apply. They should be dropped as well.
b16634a USB: io_ti: fix chars_in_buffer overhead
Needed in 3.9.
a37025b USB: ftdi_sio: fix chars_in_buffer overhead
c413364 USB: ftdi_sio: clean up get_modem_status
dcf0105 USB: serial: add generic wait_until_sent implementation
These three are also needed in 3.9 (and also 3.8).
0693196 USB: serial: add wait_until_sent operation
Needed in 3.9 (and 3.8). (You noticed my refspec did not include
it and added it.)
Sorry about the confusion.
Johan
