    eeprom: make older eeprom drivers select NVMEM_SYSFS · 1b562183
    Arseny Solokha authored
    misc/eeprom/{at24,at25,eeprom_93xx46} drivers all register their
    corresponding devices in the nvmem framework in compat mode which requires
    nvmem sysfs interface to be present. The latter, however, has been split
    out from nvmem under a separate Kconfig in commit ae0c2d72
    core: add NVMEM_SYSFS Kconfig"). As a result, probing certain I2C-attached
    EEPROMs now fails with
      at24: probe of 0-0050 failed with error -38
    because of a stub implementation of nvmem_sysfs_setup_compat()
    in drivers/nvmem/nvmem.h. Update the nvmem dependency for these drivers
    so they could load again:
