Subject: UBIFS: not build debug messages with CONFIG_UBIFS_FS_DEBUG disabled
X-Git-Tag: drm-fsl-dcu-for-next~11582^2
X-Git-Url: http://git.agner.ch/gitweb/?p=linux-drm-fsl-dcu.git;a=commitdiff_plain;h=016f1c54408b1e92e2e8087bfc05ca0a9c258513

UBIFS: not build debug messages with CONFIG_UBIFS_FS_DEBUG disabled

With
  $ grep -e UBIFS_FS_DEBUG -e DYNAMIC_DEBUG .config
  # CONFIG_UBIFS_FS_DEBUG is not set
  CONFIG_DYNAMIC_DEBUG=y

Debug messages are kept in the object files due to the
dynamic_pr_debug() macro, even if they are never going to be printed:
  $ make fs/ubifs/super.o
  $ strings fs/ubifs/super.o | grep 'compiled on'
  compiled on:         Aug 11 2011 at 12:21:38

Use plain printk to fix this.
