    kernel: mhi: backport upstream patch
    
    This patch will print the name of the modem in the bootlog
    during probing.
    
    This allows to verify that the exact model was loaded and not some
    generic type.
    
    The only other way to do this is by enabling dynamic debugging
    which is disabled by default in OpenWRT

+Subject: [PATCH] bus: mhi: host: always print detected modem name
+
+This harmless print provides a very easy way of knowing
+if the modem is detected properly during probing.
+
+Promote it to an informational print so no hassle is required
+enabling kernel debugging info to obtain it.
+
+The rationale here is that:
+On a lot of low-storage embedded devices, extensive kernel
+debugging info is not always present as this would
+increase it's size to much causing partition size issues.
