I thought I objected to this patch, but it seems to be in -next? Does
anyone know what has happened here?
I am seeing these errors now when running sandbox 'u-boot -D':
i2c_emul_find() No emulators for device 'sandbox_pmic'
sandbox_pmic_write() write error to device: 0000000018c49db0 register: 0x0!
out_set_value() PMIC write failed: -5
