| Subject | [PATCH] thermal/powerclamp: add back module device table |
| Message-ID | <sBCFI-xU-29@gated-at.bofh.it> |
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.
