====================
irda: Use ktime_t instead of timeval

This patch-set removed all uses of timeval and used ktime_t instead if
needed, since 32-bit time types will break in the year 2038.

This patch-set also used the ktime_xxx functions accordingly.
e.g.
* Used ktime_get to get the current time instead of do_gettimeofday.
* And, used ktime_us_delta to get the elapsed time directly.
====================

      irda: vlsi_ir: Replace timeval with ktime_t · 497ec1f2
      Chunyan Zhang authored 
      The vlsi ir driver uses 'timeval', which we try to remove in the kernel
because all 32-bit time types will break in the year 2038.

This patch also changes do_gettimeofday() to ktime_get() accordingly,
since ktime_get returns a ktime_t, but do_gettimeofday returns a
struct timeval, and the other reason is that ktime_get() uses
the monotonic clock.

This patch uses ktime_us_delta to get the elapsed time of microsecond,
and uses div_s64_rem to get what seconds & microseconds time elapsed
for printing.

This patch also changes the function 'vlsi_hard_start_xmit' to do the
same things as the others drivers, that is passing the remaining time
into udelay() instead of looping until enough time has passed.

This patch uses ktime_us_delta to get the elapsed time, and in this
way it no longer needs to check for the overflow, because
ktime_us_delta returns time difference of microsecond.

      irda: Removed all unused timeval variables · 270d73c1
      Chunyan Zhang authored 
      In the file au1k_ir.c & via-ircc.h, there were two unused definitions of the
timeval type members, this commit therefore removes this unneeded code.

In other three files, the same problem is the rx_time member is only ever
written, never read, so removed it entirely.
