Kevin Hilman already has got a nicer patch [1] that fixes this problem at a generic level. [1] https://lkml.org/lkml/2013/10/19/5

Earlier to commit 64c862a839a8 ("devres: add kernel standard devm_k.alloc functions") devres_alloc API used to zero-initialize the devres allocated object, but now only the devres header is zero-initialized. Since clk_register zero-initializes the memory while allocating for a new clock, passing explicit flag __GFP_ZERO to devres_alloc in devm_clk_register to match the behaviour.
