[PATCH] remove pointless debug printk in rt_ioctl_giwscan()

[PATCH] remove pointless debug printk in rt_ioctl_giwscan()

[Giangiacomo Mariotti]

This debug printk is only useful if you're debugging the staging drivers
2860 e 2870, but, if you're just using them, it becomes really annoying, because
it uselessly clobbers the kernel log. I guess this patch shouldn't really get merged,
but it's more like a request to remove these annoying debugging messages for normal users.
If I get any suggestion on how to implement this in a way acceptable to get it merged, I'll
be happy to create the "good" version  of the patch.

Thanks,

Giangiacomo

Ideally, drivers should not have their own debugging macros like this, but
instead use the kernel's own pr_debug() and (preferrably) dev_dbg() macros,
which are disabled by default.
For many of these debugging outputs, it's even better to kill them entirely
instead of converting to dev_dbg().
Do not put the line in comments though.

I agree, just use dev_dbg() instead.
