net: dsa: sja1105: round up PTP perout pin duration
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: net: dsa: sja1105: round up PTP perout pin duration pin_duration is converted from the user-provided period to SJA1105 clock ticks and is later passed as the cycle_time argument to future_base_time(). Very small period values may become zero after the conversion, which can lead to a division by zero in future_base_time(). Round zero pin_duration up to 1 tick so that the smallest unsupported periods use the minimum non-zero hardware duration instead of passing zero to future_base_time().

Solution
Round up PTP perout pin duration to prevent division by zero.
- Apply the Linux kernel patch for the sja1105 driver.
- Ensure pin_duration is rounded up to at least 1 tick.
- Update the system to the patched Linux kernel version.
