| Subject: UBI: fix debugging messages |
| |
| From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> |
| |
| 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. |
