Subject: [PATCH] ACPI / sysfs: make function param_set_trace_method_name static

From: Colin Ian King <colin.king@...onical.com>

The function param_set_trace_method_name is local to the source and does
not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'param_set_trace_method_name' was not declared. Should it be static?
