[lvc-project] [PATCH] ASoC: simple-card-utils: Fix error handling in simple_util_init_jack()

[Igor Artemiev]

Currently, if snd_soc_card_jack_new_pins() or snd_soc_jack_add_gpios()
fails, the function continues execution without handling the error.
This can lead to unexpected behavior and potential crashes.

This patch fixes the problem by checking the return value 
of these functions.
