With the newest generic spi nor driver [1] this patch shouldn't
be needed at all anymore. Could you verify, that your flash will work
without it?

Tested now, the v6.2-rc3 recognizes the chip.
Does this mean that all SFDP-supporting chips will be recognized automatically?
Tomas, we can abandon upstreaming effort, I'll save the patch if it
will needed by older kernel versions.
