[ Upstream commit 64c6a38136b74a2f18c42199830975edd9fbc379 ]
'p_clk' is an array allocated just before the for loop for all clk that need to be registered. It is incremented at each loop iteration.
If a clk_register() call fails, 'p_clk' may point to something different from what should be freed.
The best we can do, is to avoid this wrong release of memory.
