Descriptions

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd937x: fix a potential memory leak in wcd937x_soc_codec_probe() When snd_soc_dapm_new_controls() or snd_soc_dapm_add_routes() fails,
wcd937x_soc_codec_probe() returns without releasing 'wcd937x->clsh_info',
which is allocated by wcd_clsh_ctrl_alloc. Add wcd_clsh_ctrl_free()
to prevent potential memory leak.
