ASoC: imx-card: Add NULL check in imx_card_probe()
[ Upstream commit 93d34608fd162f725172e780b1c60cc93a920719 ]
devm_kasprintf() returns NULL when memory allocation fails. Currently,
imx_card_probe() does not check for this case, which results in a NULL
pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue.
