3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nishanth Menon <n...@ti.com>
commit b110547e586eb5825bc1d04aa9147bff83b57672 upstream.
Commit 9fa2df6b90786301b175e264f5fa9846aba81a65
(ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present)
makes the logic:
for (i = 0; i < opp_def_size; i++) {
<snip>
if (!oh || !oh->od) {
<snip>
continue;
}
<snip>
opp_def++;
}
In short, the moment we hit a "Bad OPP", we end up looping the list
comparing against the bad opp definition pointer for the rest of the
iteration count. Instead, increment opp_def in the for loop itself
and allow continue to be used in code without much thought so that
we check the next set of OPP definition pointers :)
