[PATCH v2] mtd: maps: remove dead select of MTD_CFI_BE_BYTE_SWAP

[PATCH v2] mtd: maps: remove dead select of MTD_CFI_BE_BYTE_SWAP

[Julian Braha]

'select' does not work on config options in a 'choice', so currently it is
possible to enable MTD_PHYSMAP_IXP4XX without MTD_CFI_BE_BYTE_SWAP.

From a previous conversation, it was decided to remove the select entirely:
https://lore.kernel.org/all/c6268184-4904-49d9-b14f-0e11dce8bdad@app.fastmail.com/

This dead select was found by kconfirm, a static analysis tool for Kconfig.

Changes since v1: remove 'select' instead of using 'depends on'

Applied to mtd/next, thanks!

[1/1] mtd: maps: remove dead select of MTD_CFI_BE_BYTE_SWAP
      commit: 94d32f1ace8ee3ef3537ac6c8e71b76a418a4762

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
