../include/linux/nvmem-provider.h:51:9: error: implicit declaration of function 'ERR_PTR' [-Werror=implicit-function-declaration]

Possibly caused by commit

  697e5a47aa12 ("rtc: add generic nvmem support")

from the rtc tree.  include/linux/nvmem-provider.h uses ERR_PTR, but
does not include err.h :-(
