[PATCH 12/12] net/Bluetooth/smp - use the correct print format

From: Kai Ye
Date: Thu May 20 2021 - 07:52:47 EST


According to Documentation/core-api/printk-formats.rst,
Use the correct print format. Printing an unsigned int value should use %u
instead of %d. Otherwise printk() might end up displaying negative numbers.
