[PATCH 6.6.y v2 0/2] mtd: spi-nor: macronix: backport Quad Input Page Program fixups

[Cheng Ming Lin]

From: Cheng Ming Lin <chengminglin at mxic.com.tw>

This is a backport of two upstream commits to 6.6.y:

  commit 798aafeffb36 ("mtd: spi-nor: macronix: Add post_sfdp fixups
  for Quad Input Page Program")
  commit 797bbaa7531f ("mtd: spi-nor: macronix: add support for
  mx66{l2, u1}g45g")

Neither commit was tagged for -stable when merged. 6.6.y also predates
commit 09e5a29fa3ad ("mtd: spi-nor: macronix: convert flash_info to new
format"), which landed in v6.10, so drivers/mtd/spi-nor/macronix.c is
still in the old INFO()/NO_SFDP_FLAGS()/FIXUP_FLAGS() macro-based
format. Both patches have been adapted to that format with no other
functional change; patch 2 depends on the macronix_qpp4b_fixups hook
introduced by patch 1.

Changes in v2:
- Patch 2: added .name for the mx66l2g45g/mx66u1g45g entries. v1 left
  them anonymous like the upstream (new-format) entries, but on 6.6.y
  drivers/mtd/spi-nor/core.c:spi_nor_match_name() does
  strcmp(name, manufacturers[i]->parts[j].name) while walking every
  manufacturer's part table to resolve a flash by name. A NULL .name
  makes that strcmp() dereference NULL as soon as the scan reaches
  either entry, i.e. an oops on any name-based spi-nor probe on the
  system, not just when probing these two parts.
