I feel it so diffcult to consider the fixing this patch more.
There are some reasons why I have become such a description.
- The purpose of this patch is the resolution of the
line over 80 characters issue
- I Wrote the code to be aware of the following:
-- Do not change the procedure
-- The shallow nest
-- To avoid the redundancy
If I do not use a function pointer, which take the form below.
if (0x00 == data[i + 2])
dev_dbg(&port->dev, "Line status status.\n");
else
dev_dbg(&port->dev, "Modem status status.\n");
if (i > limit) {
dev_dbg(&port->dev,
"Illegal escape seuences in received data\n");
return 0;
}
if (0x00 == data[i + 2])
ProcessLineStatus(qt_port, data[i + 3]);
else
ProcessModemStatus(qt_port, data[i + 3]);
return 1;
I also feel it may be...
And I am against to move the dev_dbg procedure call to
qt_status_change_check procedure because the nesting will be so deep.

I think the purpose of refactoring is the resolution of the line over 80
characters issue. I think that the separation of the patch should stop taking
because they are already applied in the linux-next tree.
Thanks.
