Subject: [PATCH AUTOSEL 4.18 55/92] lightnvm: pblk: enable line minor version
 detection

From: Matias Bjørling <mb@...htnvm.io>

[ Upstream commit 99b8dad1b6e52721904220322a947f7b75056303 ]

When recovering a line, an extra check was added when debugging was
active, such that minor version where also checked. Unfortunately,
this used the ifdef NVM_DEBUG, which is not correct.

Instead use the proper DEBUG def, and now that it compiles, also fix
the variable.
