6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Benjamin Boortz <[email protected]> commit 25cb6e9a13123d1039cdc75b446ac52e1ebdc26d upstream. The driver calls ocelot_regmap_from_resource() via <linux/mfd/ocelot.h>, which internally uses devm_regmap_init_mmio() and requires REGMAP_MMIO. The Kconfig entry does not select REGMAP_MMIO, causing a build failure when no other driver in the config happens to pull in REGMAP_MMIO: include/linux/mfd/ocelot.h:34:24: error: implicit declaration of function 'devm_regmap_init_mmio' Found by randconfig testing on arm64; tinyconfig reproducer below.
