From bf71ab8ba53081c28b960d48e0c4cd1c17588aa6 Mon Sep 17 00:00:00 2001 From: Eric Lapuyade Date: Tue, 18 Dec 2012 14:15:49 +0100 Subject: NFC: Add HCI quirks to support driver (non)standard implementations Some chips diverge from the HCI spec in their implementation of standard features. This adds a new quirks parameter to nfc_hci_allocate_device() to let the driver indicate its divergence.
