[PATCH 4.8 22/37] thermal/powerclamp: add back module device table

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

 



4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jacob Pan <jacob.jun.pan@xxxxxxxxxxxxxxx>

commit ec638db8cb9ddd5ca08b23f2835b6c9c15eb616d upstream.

Commit 3105f234e0aba43e44e277c20f9b32ee8add43d4 replaced module
cpu id table with a cpu feature check, which is logically correct.
But we need the module device table to allow module auto loading.

Fixes:3105f234 thermal/powerclamp: correct cpu support check
