There has been a lot of confusion around which platform profiles are supported on various platforms and it would be useful to have a debug method to be able to override the profile mode that is selected. I don't expect this to be used in anything other than debugging in conjunction with Lenovo engineers - but it does give a way to get a system working whilst we wait for either FW fixes, or a driver fix to land upstream, if something is wonky in the mode detection logic Signed-off-by: Mark Pearson <mpearson-lenovo@squebb.ca> --- drivers/platform/x86/thinkpad_acpi.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+)
