Subject: [PATCH] iwlwifi: dbg: mark a variable __maybe_unused
Git-commit: 281277b206f03f8e66e6d5c151d75ac9c15e066d
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430
If CONFIG_IWLWIFI_DEBUGFS is not set, the variable is assigned
but not checked, resulting in a compiler warning. Suppress it,
we need the variable for the debugfs-enabled case.
