[Dan Carpenter <dan.carpenter@oracle.com>]

Hello Codrin Ciubotariu,

The patch 50291652af52: "ASoC: atmel: mchp-pdmc: add PDMC driver"
from Mar 7, 2022, leads to the following Smatch static checker
warning:

	sound/soc/atmel/mchp-pdmc.c:186 mchp_pdmc_af_put()
	warn: this array is probably non-NULL. 'uvalue->value.integer.value'

sound/soc/atmel/mchp-pdmc.c
    181 static int mchp_pdmc_af_put(struct snd_kcontrol *kcontrol,
    182                             struct snd_ctl_elem_value *uvalue)
    183 {
    184         struct snd_soc_component *component = snd_kcontrol_chip(kcontrol);
    185         struct mchp_pdmc *dd = snd_soc_component_get_drvdata(component);
--> 186         bool af = uvalue->value.integer.value ? true : false;
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
value is an array, not a pointer.  It's always going to be non-NULL.

    189                 return 0;

    194 }
