[PATCH v3 6/17] arcmsr: precise checking adapter ID

[PATCH v3 6/17] arcmsr: precise checking adapter ID

[Ching Huang]

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.
