This patch includes below fixes to properly free clk32k clock source:
1. remove a redundant clk_put in t7l66xb_probe error path
2. add missing clk_disable(t7l66xb->clk32k) and clk_put(t7l66xb->clk32k)
   to properly free the clock source.

Patch applied to my for-next branch. This almost looks like 2.6.35 material
though.
