From 6c7ee8905d54e66d01902c59490bbc99d87d4efb Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 16 Jun 2014 12:32:33 +0300 Subject: clk: ti: apll: not allocating enough data There is a cut and paste bug here which will lead to memory corruption because we don't allocate enough data.

Remove the updating of the return variable r to 0 if MAX_APLL_WAIT_TRIES is not yet reached, because r is already 0 at this point.
