Upgraded from kernel-2.6.32 to kernel-2.6.33, and now get the following
error when compiling ltmodem.

I checked for changes within drivers/serial/serial_core.c, but couldn't
find the specific change.  (I did verify ltmodem compiles fine without
error under 2.6.32.)

Sorry.  These changes were already found and patched for kernel-2.6.32!

I just happened to spend the last 12 hours finding all the new variable
names and writing a new patch -- while the patch was already written.
:-/


For reference for those doing a Google search:

-   struct tty_struct *tty = up->port.info->port.tty;
+   struct tty_struct *tty = up->port.state->port.tty

-   struct circ_buf *xmit = &up->port.info->xmit;
+   struct circ_buf *xmit = &up->port.state->xmit;

-       wake_up_interruptible(&up->port.info->delta_msr_wait);
+       wake_up_interruptible(&up->port.state->port.delta_msr_wait)
