+Subject: [PATCH 053/130] UBI: fix debugging messages
+
+commit 72f0d453d81d35087b1d3ad7c8285628c2be6e1d upstream.
+
+Patch ab50ff684707031ed4bad2fdd313208ae392e5bb broke UBI debugging messages:
+before that commit when UBI debugging was enabled, users saw few useful
+debugging messages after attaching an MTD device. However, that patch turned
+'dbg_msg()' into 'pr_debug()', so to enable the debugging messages users have
+to enable them first via /sys/kernel/debug/dynamic_debug/control, which is
+very impractical.
+
+This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just
+as it was before the breakage.
