The ipw2x00 driver family uses get_seconds() to read the current time for various purposes. This function is deprecated because of the 32-bit time_t overflow, and it can cause unexpected behavior when the time changes due to settimeofday() calls or leap second updates.
In many cases, we want to use monotonic time instead, however ipw2x00 explicitly tracks the time spent in suspend, so this changes the driver over to use ktime_get_boottime_seconds(), which is slightly slower, but not used in a fastpath here.
