Subject: [PATCH v5 01/11] Bluetooth: Add support hdev to allocate private data
Date: Thu, 29 Jul 2021 11:35:50 -0700 [thread overview]
Message-ID: <20210729183600.281586-2-hj.tedd.an@gmail.com> (raw)
In-Reply-To: <20210729183600.281586-1-hj.tedd.an@gmail.com>
From: Tedd Ho-Jeong An <tedd.an@intel.com>
This patch adds support hdev to allocate extra size for private data.
The size of private data is specified in the hdev_alloc_size(priv_size)
and the allocated buffer can be accessed with hci_get_priv(hdev).
