hpet: 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) | \ Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Acked-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
