Subject: [PATCH] lightnvm: remove chnl_offset in nvme_nvm_identity
Git-commit: 8f37d1913f096b530242f7815ac0be3c20888ef9
Patch-mainline: v4.17-rc1

The identity structure is initialized to zero in the beginning of
the nvme_nvm_identity function. The chnl_offset is separately set to
zero. Since both the variable and assignment is never changed, remove
them.
