Subject: [PATCH] [v2] mtd: cfi: allow building spi-intel standalone
Date:   Tue, 20 Dec 2022 15:13:34 +0100

From: Arnd Bergmann <arnd@arndb.de>

When MTD or MTD_CFI_GEOMETRY is disabled, the spi-intel driver
fails to build, as it includes the shared CFI header:

include/linux/mtd/cfi.h:62:2: error: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]
   62 | #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.

linux/mtd/spi-nor.h does not actually need to include cfi.h, so
remove the inclusion here to fix the warning. This uncovers a
missing #include in spi-nor/core.c so add that there to
prevent a different build issue.

Fixes: e23e5a05d1fd ("mtd: spi-nor: intel-spi: Convert to SPI MEM")
