[SERIAL PATCH] 1672/1: Restore sizeof(struct serial_struct)
Patch from SAN People
Patch 2.4.21-rmk1 added a "iomap_base" field to the serial_struct
structure (include/linux/serial.h).
Since that structure is exported to user-space it should be
consistent between revisions of the stable 2.4 kernels.
This patch removes 4 bytes (were "reserved") to restore the size
of the structure.
Without this patch, ioctl(TIOCGSERIAL) will copy_to_user() 4
bytes more than expected and possibly corrupt the application's
stack/heap.
