mtd: rawnand: qcom: Return actual error code instead of -ENODEV
[ Upstream commit 55fbb9ba4f06cb6aff32daca1e1910173c13ec51 ]
In qcom_probe_nand_devices() function, the error code returned by
qcom_nand_host_init_and_register() is converted to -ENODEV in the case
of failure. This poses issue if -EPROBE_DEFER is returned when the
dependency is not available for a component like parser.
So let's restructure the error handling logic a bit and return the
actual error code in case of qcom_nand_host_init_and_register() failure.
Fixes: c76b78d8ec05 ("mtd: nand: Qualcomm NAND controller driver")
