1380 to 2.0.0) an entry is made into tty_io.c. A pointer to the last
1381 memory location (from kernel space) used (kmem_start) is passed
1382 to pc_init. It is pc_inits responsibility to modify this value
1383 for any memory that the Digi driver might need and then return
1384 this value to the operating system. For example if the driver
1385 wishes to allocate 1K of kernel memory, pc_init would return
1386 (kmem_start + 1024). This memory (Between kmem_start and kmem_start
1387 + 1024) would then be available for use exclusively by the driver.
1388 In this case our driver does not allocate any of this kernel
1389 memory.
