      [media] cobalt: fix 64-bit division · 95a86e43
      Hans Verkuil authored
      There are still some 64-bit division problems in the cobalt code.
      Replace it by div_u64.

      [media] rc: gpio-ir-recv: don't sleep in irq handler · 64657066
      Heiko Stübner authored
      Don't allow sleep when getting the gpio value in the irq-handler.
      On my rk3288 board this results in might_sleep warnings when receiving
      data like:

      [media] dvb-frontend: Replace timeval with ktime_t · 9056a23b
      Tina Ruchandani authored
      struct timeval uses a 32-bit seconds representation which will
      overflow in the year 2038 and beyond. This patch replaces
      the usage of struct timeval with ktime_t which is a 64-bit
      timestamp and is year 2038 safe.
      This patch is part of a larger attempt to remove all instances
      of 32-bit timekeeping variables (timeval, timespec, time_t)
      which are not year 2038 safe, from the kernel.
