SubjectRe: [PATCH] arch: arm: mach-msm: smd.c: Remove some unused functions
Hi

My script looks for the same function name, so if they then would be
named exactly the same, they would come up.

But I can not even find drivers/staging/dream/ or is this really new code?


Kind regards
Rickard Strandqvist
