From: Hauke Mehrtens Date: Fri, 2 Nov 2018 23:32:39 +0000 (+0100) Subject: kernel: Make CONFIG_NVMEM tristate X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d234431c0cc3f8d8d9a562b5ebf29bd41f77401d;p=openwrt%2Fstaging%2F981213.git kernel: Make CONFIG_NVMEM tristate CONFIG_OF_NET depends on CONFIG_NVMEM in kernel 4.19. To fix some build problems in mainline Linux kernel CONFIG_NVMEM was changed from tristate to bool in commit 2a37ce25d9 ("nvmem: disallow modular CONFIG_NVMEM"). This patch in OpenWrt revert the upstream commit and changes CONFIG_NVMEM back to tristate we just have to make sure to build this in for all targets which select CONFIG_OF_NET.
