Subject: ASoC: Fix incorrect kfree in ad193x_probe error path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=50d0ac2e1e98efa89f6dc167977b1a0d46d5e48e;p=linux-beck.git

ASoC: Fix incorrect kfree in ad193x_probe error path

We allocated memory for ad193x in ad193x_spi_probe,
and will free the memory in either ad193x_spi_probe error path or
ad193x_spi_remove.

Thus we should not call kfree(ad193x) in ad193x_probe, otherwise
we have double free of ad193x.
