Subject: [PATCH 1/5] ASoC: Fix incorrect kfree in ad1836_probe error path

We allocated memory for ad1836 in ad1836_spi_probe,
and will free the memory in either ad1836_spi_probe error path or
ad1836_spi_remove.

Thus we should not call kfree(ad1836) in ad1836_probe, otherwise
we have double free of ad1836.
