[PATCH v3 1/2] HID: spi-hid: propagate reset assertion errors during initialization

[Jizhou Tong]

Stop initialization before power-up or IRQ enablement if asserting reset
fails. Return the platform error through the core probe and frontend.
This initialization path still ignores the assertion error in v7.
