Subject: [PATCH v3 02/12] Bluetooth: cmtp: Use the correct print format
Date: Thu, 3 Jun 2021 15:40:55 +0800	[thread overview]
Message-ID: <1622706065-45409-3-git-send-email-yekai13@huawei.com> (raw)
In-Reply-To: <1622706065-45409-1-git-send-email-yekai13@huawei.com>

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.
