[alsa-devel] [PATCH 1/5] ASOC: SOF: ipc: prevent logging trace messages

[Pierre-Louis Bossart]

From: Dragos Tarcatu <dragos_tarcatu at mentor.com>

If the firmware is set for verbose tracing, the kernel log is flooded
with ipc rx/ipc rx done messages. Prevent logging those unless the
verbose IPC debugging config option is set.
