To preserve existing semantics in cases where KERN_DEBUG is indeed
appropriate, use netdev_printk(KERN_DEBUG, ...)
Convert PPPIOCDETACH to pr_warn() because an unexpected file count is

enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED
flag is set. A recent rework of enic_set_port_profile added code to reset this
flag on disassociate. As a result of which a client calling enic_get_vf_port
to get the status of port profile disassociate will always get a return value
of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate
ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the
flag is set both at associate and disassociate of a port profile.

In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate
memory via alloc_etherdev(). We then call PRIV() on the returned storage
which is 'return netdev_priv()'. netdev_priv() takes the pointer it is
passed and adds 'ALIGN(sizeof(struct net_device), NETDEV_ALIGN)' to it and
returns it. Then we test the resulting pointer for NULL, which it is
unlikely to be at this point, and later dereference it. This will go bad
if alloc_etherdev() actually returned NULL.
This patch reworks the code slightly so that we test for a NULL pointer
(and return -ENOMEM) directly after calling alloc_etherdev().

The power detector adc offset calibration has to be done
on 4 minutes interval (longcal * pa_skip_count). But the commit
"ath9k_hw: fix a noise floor calibration related race condition"
makes the PA calibration executed more frequently beased on
nfcal_pending value. Running PAOffset calibration lesser than
longcal interval doesn't help anything and the worse part is that
it causes NF load timeouts and RX deaf conditions.
In a very noisy environment, where the distance b/w AP & station
is ~10 meter and running a downlink udp traffic with frequent
background scan causes "Timeout while waiting for nf to load:
AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state.
This issue was originaly reported in Android platform where
the network-manager application does bgscan more frequently
on AR9271 chips. (AR9285 family usb device).

This patch fixes the mtdpart bug which allows users reading OOB past the
end of the partition. This happens because 'part_read_oob()' allows reading
multiple OOB areas in one go, and mtdparts does not validate the OOB
length in the request.
Although there is such check in 'nand_do_read_oob()' in nand_base.c, but
it checks that we do not read past the flash chip, not the partition,
because in nand_base.c we work with the whole chip (e.g., mtd->size
in nand_base.c is the size of the whole chip). So this check cannot
be done correctly in nand_base.c and should be instead done in mtdparts.c.
This problem was reported by Jason Liu <r64343@freescale.com> and reproduced
with nandsim:
$ modprobe nandsim first_id_byte=0x20 second_id_byte=0xaa third_id_byte=0x00 \

Second, if the reset failed, we were returning without
