Subject: [PATCH 5/5] ASoC: Fix incorrect kfree in wm8962_probe error path

We allocated memory for wm8962 in wm8962_i2c_probe,
and will free the memory in either wm8962_i2c_probe error path
or wm8962_i2c_remove.

Thus we should not call kfree(wm8962) in wm8962_probe, otherwise
we have double free of wm8962.
