The patch titled Subject: drivers/char/hpet.c: make cmd parameter of hpet_ioctl_common() unsigned has been added to the -mm tree. Its filename is hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Matthias Kaehlcke <mka@xxxxxxxxxxxx> Subject: drivers/char/hpet.c: make cmd parameter of hpet_ioctl_common() unsigned The value passed by the two callers of the function is unsigned anyway. Making the parameter unsigned fixes the following warning when building with clang: drivers/char/hpet.c:588:7: error: overflow converting case value to switch condition type (2149083139 to 18446744071563667459) [-Werror,-Wswitch] case HPET_INFO: ^ include/uapi/linux/hpet.h:18:19: note: expanded from macro 'HPET_INFO' ^ include/uapi/asm-generic/ioctl.h:77:28: note: expanded from macro '_IOR' ^ include/uapi/asm-generic/ioctl.h:66:2: note: expanded from macro '_IOC' (((dir) << _IOC_DIRSHIFT) | \ Link: http://lkml.kernel.org/r/20170313185725.144873-1-mka@xxxxxxxxxxxx Signed-off-by: Matthias Kaehlcke <mka@xxxxxxxxxxxx> Acked-by: Clemens Ladisch <clemens@xxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/char/hpet.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/char/hpet.c~hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned drivers/char/hpet.c --- a/drivers/char/hpet.c~hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned +++ a/drivers/char/hpet.c @@ -575,7 +575,7 @@ static inline unsigned long hpet_time_di } static int -hpet_ioctl_common(struct hpet_dev *devp, int cmd, unsigned long arg, +hpet_ioctl_common(struct hpet_dev *devp, unsigned int cmd, unsigned long arg, struct hpet_info *info) { struct hpet_timer __iomem *timer; _ Patches currently in -mm which might be from mka@xxxxxxxxxxxx are hpet-make-cmd-parameter-of-hpet_ioctl_common-unsigned.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
