ASoC: amd: Fix potential NULL pointer dereference
Check return value from call to devm_kzalloc() in order to prevent a potential NULL pointer dereference. Also, notice that it makes no sense to allocate any resources if res = platform_get_resource(pdev, IORESOURCE_MEM, 0); fails, so move the call to devm_kzalloc() below the mentioned code. Lastly, improve the use of sizeof in the call to devm_kzalloc() by changing it from sizeof(struct i2s_dev_data) to sizeof(*adata) This issue was detected with the help of Coccinelle.
