+Subject: [PATCH] brcmfmac: Do not print the firmware version as an error
+
+Using pr_err for things which are not errors is a bad idea. E.g. it
+will cause the plymouth bootsplash screen to drop back to the text
+console so that the user can see the error, which is not what we
+normally want to happen.
+
+Instead add a new brcmf_info macro and use that.
