[PATCH 2/4] Move hp_accel to drivers/platform/x86

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The hp_accel driver isn't a hardware monitoring driver, so it doesn't
belong to drivers/hwmon. Move it to drivers/platform/x86, assuming HP
doesn't ship non-x86 laptops.

Not tested due to lack of hardware.
