Subject: [PATCH 137/146] iwlwifi: fix fw_pre_next_step to apply also for C
step
Git-commit: e9fb92e13d5e743a6ff13d3206c0f9e5e8cbc1f4
Patch-mainline: v4.13-rc6
References: FATE#322675
C step NICs should use the latest FW (currently B step).
Correct the condition to make C step NICs advanced its default FW name
to the latest one.
Also rename _next_ to b_or_c to avoid confusion.
Fixes: 5da083d1922c ("iwlwifi: add support for 9000 HW B-step NICs")
