returned to userspace via the RTC_WKALRM_RD ioctl, uninitialized\nkernel stack data residing in these holes may be leaked.\n\nZero-initialize the struct at declaration to eliminate this information\nleak risk.\n\nFixes smatch warnings:\n- drivers/rtc/dev.c:392 rtc_dev_ioctl() warn: check that 'alarm' doesn't\n  leak information (struct has a hole after
