[PATCH v3 36/41] mtd: spi-nor: micron-st: sort flash_info database

Michael Walle mwalle at kernel.org
Fri Sep 8 03:16:54 PDT 2023


The flash ID is the new primary key into our database. Sort the entry by
it. Keep the most specific ones first, because there might be ID
collisions between shorter and longer ones.
