From cfe417bc47ba8f470941a1b8ad60911e163f1b34 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 26 Aug 2015 12:22:12 +0200 Subject: [PATCH] iwlwifi: mvm: don't NUL-terminate low-latency debugfs file There's obviously no reason to write a NUL-terminating byte into the debugfs file. Apparently nobody tried to use this from a tool that doesn't strip NUL bytes though, so we never noticed. Fix it.
