Subject: mtd: spi-nor: sst: sort flash_info database
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1de410815768295c8ce3c0289d7fc29762e3ca76;p=linux.git

mtd: spi-nor: sst: sort flash_info database

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.
