Subject: [PATCH v3 6/17] arcmsr: precise checking adapter ID
Date: Tue, 19 Aug 2014 14:55:57 +0800 [thread overview]
Message-ID: <1408431357.4748.41.camel@Centos6.3-64> (raw)
From: Ching Huang <ching2048@areca.com.tw>
change since v2:
1. This patch pre-define the adapter->type in private data of struct pci_device_id.
2. Remove arcmsr_define_adapter_type function.
