Pull MTD updates from Miquel Raynal:
 "MTD changes:

   - No particularly important patchset this cycle, but we have a few
     usual improvements: like using a better/more recent helper or
     checking a return value.

  Raw NAND changes:

   - The use of for_each_child_of_node_scoped() has been spread into the
     subsystem drivers

   - a couple of exit path have been fixed (mtk, denali)

   - TI GPMC bindings have been enhanced to comply with up-to-date
     partition descriptions

   - a load of small and misc fixes

  SPI-NAND changes:

   - The most impacting series this cycle is bringing support for
     continuous reads in the SPI-NAND subsystem.

     This is a feature already merged in the raw NAND subsystem which
     allows optimizing the internal fetch times in the chip while
     reading sequential pages within an eraseblock.

     For now only Macronix NANDs benefit from this feature. While we are
     talking about Macronix, some of their chip need an explicit action
     for selecting a different plane, and support for it has also been
     brought.

   - The bitflip threshold has also been set to the same arbitrary level
     as in the raw NAND subsystem to optimize wear leveling decisions

   - Add upport for a new Winbond chip

  SPI NOR changes:

   - Add Write Protect support for N25Q064A.

   - New flash support for Zetta ZD25Q128C and Spansion S28HS256T.

   - Fix a NULL dereference in probe path for flashes without a name.

     The probe path tries to access the name without checking its
     existence first. S28HS256T is the first flash to define its entry
     without a name, uncovering this issue"
