0d7760f230 arm64: dts: broadcom: bcmbca: Update router boards
Enable the nand controller and add WP pin connection property in actual
board dts as they are board level properties now that they are disabled
and moved out from SoC dtsi.

Also remove the unnecessary brcm,nand-has-wp property from AC5300 board.
This property is only needed for some old controller that this board
does not apply.

e395036504 mtd: rawnand: Prefer struct_size over open coded arithmetic
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1].

As the "chip" variable is a pointer to "struct mtk_nfc_nand_chip" and
this structure ends in a flexible array:

struct mtk_nfc_nand_chip {
	[...]
	u8 sels[] __counted_by(nsels);
};

the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the argument "size + count * size" in the
devm_kzalloc() function.

This way, the code is more readable and safer.

4bd14b2fd8 mtd: spinand: esmt: Extend IDs to 5 bytes
According to the datasheets, the ESMT chips in question will return a 5
byte long identification code where the last 3 bytes are the JEDEC
continuation codes (7Fh). Although, I would have expected 4 continuation
codes as Powerchip Semiconductor (C8h, corresponding to the parameter
page data) is located in bank 5 of the JEDEC database.

By matching the full 5 bytes we can avoid clashes with GigaDevice NAND
flashes.

This fix allows the MT7688-based GARDENA smart Gateway to boot again.

34a956739d mtd: spinand: Add support for 5-byte IDs
E.g. ESMT chips will return an identification code with a length of 5
bytes. In order to prevent ambiguity, flash chips would actually need to
return IDs that are up to 17 or more bytes long due to JEDEC's
continuation scheme. I understand that if a manufacturer ID is located
in bank N of JEDEC's database (there are currently 16 banks), N - 1
continuation codes (7Fh) need to be added to the identification code
(comprising of manufacturer ID and device ID). However, most flash chip
manufacturers don't seem to implement this (correctly).

ec4edd7b9d bcachefs: Prep work for variable size btree node buffers
bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.

And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.

Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

======================================================

In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.

Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().
