Subject: [PATCH] mtd: cfi: allow building spi-intel standalone
From: Arnd Bergmann <arnd@...db.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.
Use an #ifdef here to guard the settings so the header can be included
in all configurations.
Fixes: e23e5a05d1fd ("mtd: spi-nor: intel-spi: Convert to SPI MEM")
