nvme-pci: nvme.quirks= on the kernel command line hangs early boot when nvme-pci is built in

[Ramón Jesús Miranda]

Hi,

Passing nvme.quirks=VID:DID:QUIRKS on the kernel command line with
CONFIG_BLK_DEV_NVME=y hangs the kernel immediately, before any console
output, on arm64 (Microsoft Surface Pro 11, X1E80100, 7.2.8).

As far as I can tell, quirks_param_set() runs during parse_args() for
built-in modules, i.e. before memory management is initialised, and it
allocates there. As a module (nvme.quirks= handled at module load) it
works.

Removing the parameter boots normally. I have not checked other
architectures.
