pr_debug usage in raw_sendmsg

pr_debug usage in raw_sendmsg

[Dave Jones]

While working on my system call fuzzer, I keep getting a lot
of spew in dmesg from raw_sendmsg. Particularly..

[ 6442.690780] no dev
[ 6454.257701] msg_flags 0x00000080
[ 8055.873142] msg->msg_flags = 0xd63f35c1

Is there a good reason for keeping -DDEBUG in net/ieee802154/Makefile ?

Those messages don't look particularly helpful given there's no other context.
(the 'no dev' one in particular looks kinda hopeless)

All of those cflags modifications in net/ieee802154/Makefile are bogus,
I'll commit the following:

--------------------
ieee802154: Remove hacked CFLAGS in net/ieee802154/Makefile

It adds -Wall (which the kernel carefully controls already) and of all
things -DDEBUG (which should be set by other means if desired, please
we have dynamic-debug these days).

Kill this noise.
