platform/x86: thinkpad_acpi: Fix lkp-tests warnings for platform profiles
[ Upstream commit f999e23ce66c1555d7b653fba171a88ecee53704 ] Fix issues identified in dytc_profile_refresh identified by lkp-tests. drivers/platform/x86/thinkpad_acpi.c:10538 dytc_profile_refresh() error: uninitialized symbol 'funcmode'. drivers/platform/x86/thinkpad_acpi.c:10531 dytc_profile_refresh() error: uninitialized symbol 'output'. drivers/platform/x86/thinkpad_acpi.c:10537 dytc_profile_refresh() error: uninitialized symbol 'output'. These issues should not lead to real problems in the field as the refresh function should only be called if MMC or PSC mode enabled. But good to fix. Thanks to Dan Carpenter and the lkp-tests project for flagging these.
