This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 608cfbe4abaf76e9d732efd7ed1cfa3998163d91 upstream.
The call to clamp_t() first truncates the variable signed 8 bit and as a
result, the actual clamp is a no-op.
Fixes: 0d78156eef1d ('p54: improve site survey')
