Subject: [PATCH 1/1] Bluetooth: add printf format attribute to hci_set_[fh]w_info()
Date: Fri, 29 Jul 2016 13:28:25 +0200 [thread overview]
Message-ID: <20160729112825.22091-1-nicolas.iooss_linux@m4x.org> (raw)
Commit 5177a83827cd ("Bluetooth: Add debugfs fields for hardware and
firmware info") introduced hci_set_hw_info() and hci_set_fw_info().
These functions use kvasprintf_const() but are not marked with a
__printf attribute. Adding such an attribute helps detecting issues
related to printf-formatting at build time.
