Aleksandr Mishin f9f7f29f64 ASoC: qcom: Adjust issues in case of DT error in asoc_qcom_lpass_cpu_platform_probe() ... If IORESOURCE_MEM "lpass-rxtx-cdc-dma-lpm" or "lpass-va-cdc-dma-lpm" resources is not provided in Device Tree due to any error, platform_get_resource_byname() will return NULL which is later dereferenced. According to sound/qcom,lpass-cpu.yaml, these resources are provided, but DT can be broken due to any error. In such cases driver must be able to protect itself, since the DT is external data for the driver. Adjust this issues by adding NULL return check. Found by Linux Verification Center (linuxtesting.org) with SVACE.
