[RFC PATCH] phy: qcom: ipq4019-usb: Propagate reset operation failures

[Pengpeng Hou]

Hi Konrad,

Your comments on the declaration layout and unchecked rollback return
are valid. Rechecking the provider exposed a more fundamental limitation
in the RFC's premise: the in-tree IPQ4019 DT uses GCC resets, and
qcom_reset_set_assert() returns zero after the regmap operations.

I therefore do not have evidence that the hardware-failure case described
in the RFC is reported through this provider. Generic reset API errors
alone do not establish that case on this platform.

Please keep this RFC on hold. I will not respin it as a demonstrated
IPQ4019 bug fix based only on the local return-value checks.

Thanks,
Pengpeng
