I get nasty warning for each file compiled: CC drivers/video/sa1100fb.o In file included from include/asm/bitops.h:23, from include/linux/bitops.h:9, from include/linux/thread_info.h:20, from include/linux/preempt.h:9, from include/linux/spinlock.h:49, from include/linux/module.h:9, from drivers/video/sa1100fb.c:163: include/asm/system.h: In function `adjust_cr': include/asm/system.h:185: warning: implicit declaration of function `local_irq_save' include/asm/system.h:192: warning: implicit declaration of function `local_irq_restore' include/asm/system.h:179: warning: unused variable `cr' Plus compile error. It should be some search&replace I should do, but which one? drivers/video/sa1100fb.c:1447:49: macro "INIT_WORK" passed 3 arguments, but takes just 2 drivers/video/sa1100fb.c: In function `sa1100fb_init_fbinfo': drivers/video/sa1100fb.c:1447: error: `INIT_WORK' undeclared (first use in this function) drivers/video/sa1100fb.c:1447: error: (Each undeclared identifier is reported only once drivers/video/sa1100fb.c:1447: error: for each function it appears in.) drivers/video/sa1100fb.c: At top level: drivers/video/sa1100fb.c:1204: warning: `sa1100fb_task' defined but not used make[2]: *** [drivers/video/sa1100fb.o] Error 1 make[1]: *** [drivers/video] Error 2 make: *** [drivers] Error 2 INIT_WORK(&fbi->task, sa1100fb_task, fbi); ... /* * Our LCD controller task (which is called when we blank or unblank) * via keventd. */ static void sa1100fb_task(void *dummy) { struct sa1100fb_info *fbi = dummy; u_int state = xchg(&fbi->task_state, -1); set_ctrlr_state(fbi, state); } (Or will I need to play with container_of or something? I guess I did not pay attetion to workqueue stuff).
