Compilation breaks while I try to compile with this patch. Do I missing anything? Below is the error I am getting,
drivers/soc/qcom/qcom_smem.c: In function ‘qcom_smem_probe’: drivers/soc/qcom/qcom_smem.c:274:2: error: implicit declaration of function ‘of_hwspin_lock_request’ [-Werror=implicit-function-declaration] smem->hwlock = of_hwspin_lock_request(pdev->dev.of_node, NULL)
Thanks, --Kiran
