Subject: parisc: Drop the pa7300lc LPMC handler
X-Git-Tag: v6.6.7~2077^2~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=390a2086a4c6a325d9cc4e3e22b68b440a08cd9f;p=platform%2Fkernel%2Flinux-starfive.git

parisc: Drop the pa7300lc LPMC handler

This was actually never really used, and the info it
prints won't help. Drop it.
