$ git bisect good 6328536ff28ca26f2ad4e6f2c956c467acebda88 is the first bad commit commit 6328536ff28ca26f2ad4e6f2c956c467acebda88 Author: Eric Anholt eric@anholt.net Date: Fri Nov 2 14:35:06 2018 -0700

This requires that the caller make a little (stack) allocation to store

v2: Use gbm_format_canonicalize (suggested by Daniel)
