Subject[PATCH] clk: Zero-initialize memory for new clock in devm_clk_register
Date
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.
