On Qcom UFS platforms, the reset control line seems to be optional (for SoCs like MSM8996 and probably for others too). The current logic tries to mimic the devm_reset_control_get_optional() API but it also continues the probe if there is an error with the declared reset line in DT/ACPI. In an ideal case, if the reset line is not declared in DT/ACPI, the probe should continue. But if there is problem in acquiring the declared reset line (like EPROBE_DEFER) it should fail and return the appropriate error code.
