[PATCH v3 02/12] Bluetooth: cmtp: Use the correct print format

From: Kai Ye
Date: Thu Jun 03 2021 - 03:44:23 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.
