[alsa-devel] [PATCH v2] ASoC: intel: Don't print FW version repeatedly

[Takashi Iwai]

Intel SST driver spews an info message "FW Versoin xxxx" at each time
the device gets initialized.  Since it's triggered at each PM (or even
runtime PM), it appears too frequently, which is rather annoying.
Moreover, the firmware in the driver is cached, thus it's assured to
be always the same version once after loaded; i.e. it's superfluous to
show the same version number repeatedly.

This patch suppresses the superfluous messages by replacing with
dev_info_once().
