/**
It doesn't make any more sense to have a opaque pointer set up by the nvmem device. Usually, the layout isn't associated with a particular nvmem device. Instead, let the caller who set the post process callback provide the priv pointer. Signed-off-by: Michael Walle <michael@walle.cc> --- changes since v2: - don't drop the pointer but let the user specify an opaque pointer changes since v1: - new patch drivers/nvmem/core.c | 4 +++- include/linux/nvmem-provider.h | 5 ++++- 2 files changed, 7 insertions(+), 2 deletions(-)
