nubus: Fix log spam
Testing shows that a single Radius PrecisionColor 24X display board, which has 95 functional resources, produces over a thousand lines of log messages. Suppress these messages with pr_debug(). Remove some redundant messages relating to nubus_get_subdir() calls. Fix the format block debug messages as the sequence of entries is backwards (my bad). Move the "scanning slots" message to its proper location. Fixes: 71ae40e4cf33 ("nubus: Clean up printk calls") Tested-by: Stan Johnson <userm57@yahoo.com> Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
