Subject: scsi: smartpqi: fix time handling
From: Arnd Bergmann <arnd@xxxxxxxx>
commit ed10858eadd4988260c6bc7d75fc25176342b5a7 upstream.
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.
Fixes: 6c223761eb54 ("smartpqi: initial commit of Microsemi smartpqi driver")
