From: Matias Bjørling Date: Fri, 13 Jul 2018 08:48:37 +0000 (+0200) Subject: lightnvm: move NVM_DEBUG to pblk X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=880eda544097a525b669df84533f439fb031684b;p=openwrt%2Fstaging%2Fblogic.git lightnvm: move NVM_DEBUG to pblk There is no users of CONFIG_NVM_DEBUG in the LightNVM subsystem. All users are in pblk. Rename NVM_DEBUG to NVM_PBLK_DEBUG and enable only for pblk. Also fix up the CONFIG_NVM_PBLK entry to follow the code style for Kconfig files.
