When iwlwifi is compiled w/o debug, we get
this warning:
iwl-agn.c: In function ‘iwlagn_load_firmware’:
iwl-agn.c:2014: warning: passing argument 3 of ‘iwl_print_hex_dump’ discards qualifiers from pointer target type
iwl-debug.h:73: note: expected ‘void *’ but argument is of type ‘const u8 *’
because the const qualifier is missing in the
inline stub. Fix this.

On AR5008-AR9002, other forms of calibration must not be started while
the noise floor calibration is running, as this can create invalid
readings which were sometimes not even recoverable by any further
calibration attempts.
This patch also ensures that the result of noise floor measurements
are processed faster and also allows the result of the initial
calibration on reset to make it into the NF history buffer

The noise floor history buffer is currently not kept per channel, which
can lead to problems when changing channels from a clean channel to a
noisy one. Also when switching from HT20 to HT40, the noise floor
history buffer is full of measurements, but none of them contain data
for the extension channel, which it needs quite a bit of time to recover
from.
This patch puts all the per-channel calibration data into a single data
structure, and gives the the driver control over whether that is used
per-channel or even not used for some channels.
For ath9k_htc, I decided to keep this per-channel in order to avoid
creating regressions.
For ath9k, the data is kept only for the operating channel, which saves
some space. ath9k_hw takes care of wiping old data when the operating
channel or its channel flags change.

Previously the software scan callback was used to indicate to the hardware,
when it was safe to calibrate. This didn't really work properly, because it
depends on a specific order of software scan callbacks vs. channel changes.
Also, software scans are not the only thing that triggers off-channel
activity, so it's better to use the newly added indication from mac80211 for
this and not use the software scan callback for anything calibration related.
This fixes at least some of the invalid noise floor readings that I've seen
in AP mode on AR9160

The periodic noise floor calibration is broken on this chip family, because
it keeps triggering a software-filtered noise floor calibration, but never
reads the result before uploading the history buffer value to the hardware.
Fix this with a call to ath9k_hw_getnf(), just like on AR9002.

On AR9003 the initial noise floor calibration is currently triggered
at the end of the reset without allowing the hardware to update the
baseband settings. This could potentially make scans in noisy
environments a bit more unreliable, so use the same calibration
sequence that is used on AR9002.

iwlwifi: queue user-initiated scan when doing internal scan
introduced a potential deadlock because it calls
ieee80211_scan_completed() with the priv->mutex
held, but mac80211 may call back into iwlwifi
which would lead to recursive locking. Move this
out from under the mutex.

The current strategy in ib_srp for posting receive buffers is:
* Post one buffer after channel establishment.
* Post one buffer before sending an SRP_CMD or SRP_TSK_MGMT to the target.
As a result, only the first non-SRP_RSP information unit from the
target will be processed. If that first information unit is an
SRP_T_LOGOUT, it will be processed. On the other hand, if the
initiator receives an SRP_CRED_REQ or SRP_AER_REQ before it receives a
SRP_T_LOGOUT, the SRP_T_LOGOUT won't be processed.
We can fix this inconsistency by changing the strategy for posting
receive buffers to:
* Post all receive buffers after channel establishment.
* After a receive buffer has been consumed and processed, post it again.
A side effect is that the ib_post_recv() call is moved out of the SCSI
command processing path. Since __srp_post_recv() is not called
directly any more, get rid of it and move the code directly into
srp_post_recv(). Also, move srp_post_recv() up in the file to avoid a
forward declaration.

Since commit 18c6182bae0acca220ed6611f741034d563cd19f ("Rework
probing/JEDEC code"), m25p80 driver successfully registers chips
even if JEDEC probing fails.
This was needed to support non-JEDEC flashes. Though, it appears
that some platforms (e.g. blackfin bf533 stamp[1]) used the old
behavior to detect if there's any flash connected, so the driver
have to fail on JEDEC probing errors.
This patch restores the old behavior for JEDEC flashes, and adds
"-nonjedec" SPI device IDs for M25Pxx flashes, so that the kernel
still supports non-JEDEC flashes.

Marvell 88ec048 is a derivative of its 88e1121r device. From the programmer's

preambles.
