mtd: spinand: Do not update the QE bit on devices without one (2026-09-25 16:53:51 +0200)

----------------------------------------------------------------
The most important set of fixes are around the handling of the QE bit in SPI NAND.

There are also a couple of behavioral fixes (mutex issue in SPI-NOR, spurious bitflips on vf610_nfc, OOB bytes count in SPI NAND and cfi_cmdset stack usage).

The rest is mostly AI fuzzing results.

----------------------------------------------------------------
Han Xu (1):
mtd: spinand: Enable QE on all dies

Karl Mehltretter (3):
mtd: core: avoid double-free of OTP NVMEM device
mtd: core: call _get_device() with the master MTD
mtd: cfi_cmdset_0001: shrink do_write_buffer() stack frame

Mehmet Fide (2):
mtd: rawnand: vf610_nfc: fix reads on chips with more than 64 bytes of OOB
mtd: rawnand: vf610_nfc: fix false bitflips on reads of erased pages

Menachem Adin (1):
mtd: mtd_intel_dg: reset poll counter for each erase

Nuno Sá (2):
mtd: spinand: fix NULL pointer dereference with no ECC engine
mtd: spinand: fix zero oobavail when no ECC engine is used

Pei Xiao (1):
mtd: block2mtd: Fix divide error when erase_size is zero

Runyu Xiao (2):
mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ
mtd: spi-nor: core: Fix mutex leak in spi_nor_rww_start_exclusive()

Sagnik Sasmal (1):
mtd: spinand: Do not update the QE bit on devices without one
