It was the only one of the drivers/nvmem/ to do that.  Three other
drivers use a pattern where they merge read and write operations into a
single access function with a type=read/write parameter, so const safety
can’t work there and I’ll continue casting from const void * to void *
in the write function to keep that pattern working.
