[PATCH] ASoC: simple-card: Dereference pointer for memcpy sizeof in asoc_simple_card_probe

[Nathan Chancellor]

Clang warns:

sound/soc/generic/simple-card.c:462:6: warning: argument to 'sizeof' in
'memcpy' call is the same pointer type 'struct asoc_simple_dai *' as the
source; expected 'struct asoc_simple_dai' or an explicit length
[-Wsizeof-pointer-memaccess]
                                        sizeof(priv->dai_props->cpu_dai));
                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Commit 4fb7f4df49d3 ("ASoC: simple-card: use cpu/codec pointer on
simple_dai_props") updated {cpu,codec}_dai to be pointers in struct
simple_dai_props but didn't update these locations to dereference the
pointers to get the proper size of their contents.
