Changes to lpt driver: - ansi prototypes in lpt.c - a bit of tidying in lpt.c - ioctl in lpt.c for switching between polling and using interrupts - added lpt.h - needed for ioctl to allow switching between polling and interrupt-driven modes. 1994-04-06 16:42:33 +00:00			`/*`

Cleaned up all headers that include <sys/ioctl.h> or <sys/ioccom.h>: - don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h> instead. This was already done in 4.4Lite for the most important ioctl headers. Header spam currently increases kernel build times by 10-20%. There are more than 30000 #includes (not counting duplicates) for compiling LINT. - include <sys/types.h> if and only it is necessary to make the header almost self-sufficient (some ioctl headers still need structs from elsewhere). - uniformized idempotency ifdefs. Copied the style in the 4.4Lite ioctl headers. 1996-09-21 14:59:43 +00:00			`#ifndef _MACHINE_LPT_H_`
