    irda: nsc-ircc: Replace timeval with ktime_t · 4c3bd197
    Chunyan Zhang authored
    The nsc ircc 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, and in this
    way it no longer needs to check for the overflow, because
    ktime_us_delta returns time difference of microsecond.
