[PATCH] of: property: fw_devlink: fixup return value check of strcmp_suffix in parse_gpios

[Li Chen]

From: Li Chen <lchen@xxxxxxxxxxxxx>

This commit addresses an issue where enabling fw_devlink=on was causing
a PCIe malfunction, resulting in endpoints missing.
After thorough investigation, it was determined that the root cause was
an incorrect usage of strcmp_suffix in parse_gpios.

Fixes: d473d32c2fba ("of: property: fw_devlink: do not link ".*,nr-gpios"")
