Hi,

in file 'drivers/gpu/drm/nouveau/nvkm/subdev/secboot/gm20b.c', error handling in 'gm20b_tegra_read_wpr()' seams to be broken.

The code used is:

mc = ioremap(TEGRA_MC_BASE, 0xd00); if (!mc) { nvkm_error(&sb->subdev, "..."); return PTR_ERR(mc); }

so we always return '0', which means success.

Best regards,

CJ
