I tried to ping Jeff Garzik about doing a driver bug fix run in order to fix this, but he hasn't shown any signs of life. So I'll do it myself later tonight. :-/ > net/sched/sch_generic.c: In function 'dev_watchdog': > net/sched/sch_generic.c:224: warning: unused variable 'drivername' Sucky, if WARN_ONCE() evaluates to nothing the sprintf() string buffer on the stack looks unused. > drivers/rtc/rtc-ds1286.c: In function 'ds1286_rtc_read': > drivers/rtc/rtc-ds1286.c:33: error: implicit declaration of function '__raw_readl' > drivers/rtc/rtc-ds1286.c: In function 'ds1286_rtc_write': > drivers/rtc/rtc-ds1286.c:38: error: implicit declaration of function '__raw_writel' > drivers/rtc/rtc-ds1286.c: In function 'ds1286_probe': > drivers/rtc/rtc-ds1286.c:345: error: implicit declaration of function 'ioremap' > drivers/rtc/rtc-ds1286.c:345: warning: assignment makes pointer from integer without a cast > drivers/rtc/rtc-ds1286.c:365: error: implicit declaration of function 'iounmap' Missing asm/io.h include. > drivers/rtc/rtc-m48t35.c: In function 'm48t35_read_time': > drivers/rtc/rtc-m48t35.c:59: error: implicit declaration of function 'readb' > drivers/rtc/rtc-m48t35.c:60: error: implicit declaration of function 'writeb' > drivers/rtc/rtc-m48t35.c: In function 'm48t35_probe': > drivers/rtc/rtc-m48t35.c:168: error: implicit declaration of function 'ioremap' > drivers/rtc/rtc-m48t35.c:168: warning: assignment makes pointer from integer without a cast > drivers/rtc/rtc-m48t35.c:188: error: implicit declaration of function 'iounmap' Likewise. > drivers/net/wireless/libertas_tf/if_usb.c: In function '__if_usb_submit_rx_urb': > drivers/net/wireless/libertas_tf/if_usb.c:334: warning: cast to pointer from integer of different size I've seen this one on sparc64 too, I think the arg is totally unused in the end for this callback control flow and we can just use NULL or zero instead.
