[Raspberry pi4] Missing regmap-i2c in modloop
In v3.12.0 the modloop contained the regmap-i2c module
squashfs-root/modules/5.4.43-0-rpi4/kernel/drivers/base/regmap
squashfs-root/modules/5.4.43-0-rpi4/kernel/drivers/base/regmap/regmap-i2c.ko
squashfs-root/modules/5.4.43-0-rpi4/kernel/drivers/base/regmap/regmap-mmio.ko
squashfs-root/modules/5.4.43-0-rpi4/kernel/drivers/base/regmap/regmap-spi.ko
but the v3.12.1 modloop is missing both the i2c and mmio modules:
squashfs-root/modules/5.4.72-0-rpi4/kernel/drivers/base/regmap
squashfs-root/modules/5.4.72-0-rpi4/kernel/drivers/base/regmap/regmap-spi.ko
I'm not sure which kernel config is responsible for this, but the seeed microphone arrays stopped working due to this, and maybe other hats as well.
