From ed10858eadd4988260c6bc7d75fc25176342b5a7 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 17 Feb 2017 16:03:52 +0100 Subject: [PATCH] scsi: smartpqi: fix time handling When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly.
