From 2fb037b89a3125627f02c40af3e3d38c3228184b Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Fri, 13 Sep 2013 13:14:21 +0800 Subject: ACPI / IPMI: Cleanup several acpi_ipmi_device members This (trivial) patch: 1. Deletes a member of the acpi_ipmi_device, smi_data, which is not actually used. 2. Updates a member of the acpi_ipmi_device, pnp_dev, which is only used by dev_warn() invocations, so changes it to a struct device.
