I agree completely. Apparently there's a coccicheck flagging constructs like this; perhaps that should be addressed. Julia? Things like: drivers/gpu/drm/tegra/gem.c:457:1-3: WARNING: PTR_ERR_OR_ZERO can be used leading to: - if (IS_ERR(bo)) - return PTR_ERR(bo); - - return 0; + return PTR_ERR_OR_ZERO(bo); I think we have consensus the error path and the happy day scenarios should remain distinct. Moreover, I find PTR_ERR_OR_ZERO() causes me to pause for a moment while the original is a crystal clear immediately.
