Trying to build the Intel SCU Watchdog fails for me with gcc 4.6.0 -
$ gcc --version | head -n 1
gcc (GCC) 4.6.0 20110513 (prerelease)
like this :
CC drivers/watchdog/intel_scu_watchdog.o
In file included from drivers/watchdog/intel_scu_watchdog.c:49:0:
/home/jj/src/linux-2.6/arch/x86/include/asm/apb_timer.h: In function ʽapbt_time_initʼ:
/home/jj/src/linux-2.6/arch/x86/include/asm/apb_timer.h:65:42: warning: ʽreturnʼ with a value, in function returning void [enabled by default]
drivers/watchdog/intel_scu_watchdog.c: In function ʽintel_scu_watchdog_initʼ:
drivers/watchdog/intel_scu_watchdog.c:468:2: error: implicit declaration of function ʽsfi_get_mtmrʼ [-Werror=implicit-function-declaration]
drivers/watchdog/intel_scu_watchdog.c:468:32: warning: assignment makes pointer from integer without a cast [enabled by default]
cc1: some warnings being treated as errors
make[1]: *** [drivers/watchdog/intel_scu_watchdog.o] Error 1
make: *** [drivers/watchdog/intel_scu_watchdog.o] Error 2
Additionally, linux/types.h is needlessly being included twice in
drivers/watchdog/intel_scu_watchdog.c
This patch fixes it all and I can now build the code.
