See the patch: https://lore.kernel.org/r/20210830083449.1.I38e95343209fe1f808c3b4860795a00a2b539701@changeid ...and Greg has applied it. I got a message 6 days ago saying it was in: git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. That being said, if people think that we should _also_ select NVMEM for this driver then I have no objections. The use of nvmem in this driver predates my patch. -Doug
