soc/tegra: fuse: Move register mapping check (1f1607db) · Commits · 戴 / test

The tegra_read_chipid() function can be called from places other than tegra_get_chip_id(), so the check for a valid mapping of the MISC registers needs to be moved to tegra_read_chipid() to catch all potential accesses. Signed-off-by:
