ASoC: mediatek: mt8192: Check existence of dai_name before dereferencing
Following commit 13f58267cda3 ("ASoC: soc.h: don't create dummy
Component via COMP_DUMMY()"), the dai_name field is only populated for
dummy components after the card is registered. This causes a null
pointer dereference in the mt8192-mt6359 sound card driver's probe
function when searching for a dai_name among all the card's dai links.
Verify that the dai_name is non-null before passing it to strcmp. While
at it, also check that there's at least one codec.
