[PATCH 1/1] Bluetooth: add printf format attribute to hci_set_[fh]w_info()

[PATCH 1/1] Bluetooth: add printf format attribute to hci_set_[fh]w_info()

[Nicolas Iooss]

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.

Hello,
After I sent the following patch a few weeks ago, I have not received
any feedback. Could you please review it?

Thanks,
Nicolas
