There is no need to use hex_dump_to_buffer() in the cases like this:
hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */
sprintf("%s\n", outbuf);
since it maybe easily converted to simple:
sprintf("%*ph\n", len, buf);
Note: it seems in one case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

CMD_SYNC is really 0 which is confusing:
if (cmd.flags & CMD_SYNC) is always false.
Fix this by simply removing its definition.

These two flags are used for the same purpose, just
combine them into a no-ir flag to annotate no initiating
radiation is allowed.
Old userspace sending either flag will have it treated as
the no-ir flag. To be considerate to older userspace we
also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.
Update all places in the tree using these flags with the
following semantic patch:

There's no need to have 'forward' debugfs function declarations
as part of the macros because the macros are always used after
the static functions are defined already, so remove them.

If on iwl_dump_nic_event_log() error occurs before that function
initialize buf, we process uninitiated pointer in
iwl_dbgfs_log_event_read() and can hit "BUG at mm/slub.c:3409"

This allows to test fw restart flow. The hook in transport
layer doesn't really make the fw assert. Moving this hook
to the op_mode allows to use the fw API to actually send a
host command that will make the fw assert.
Change the restart_fw module parameter to be a boolean on
the way.

Since we will have several forms of NVM (EEPROM, OTP, etc.)
and they will have different layouts, make the parsed data
more generic. This allows functional code to be independent
of a specific layout.
Also change some variables and function names from having
"eeprom" to "nvm" in their name.

The flush_control parameter to iwlagn_txfifo_flush
is passed as an internal value (context flags) and
then sent to the device, that can't be right.
Fix the confusion by removing the parameter, always
use IWL_DROP_ALL that is redefined according to the
firmware API in the flush control.

The generic part of the driver now creates all debugfs
directories. It creates a root directory directly in
the the root of the debugfs filesystem and within that
directories for each device, named after the device ID
of the devices iwlwifi is attached to.
In the cfg80211/mac80211 directory there's now a link
to the toplevel iwlwifi debugfs directory to make it
easier to find the debugfs files.

'echo 1 > log_event' generates the bogus "MAC is in deep sleep"
or "Timeout waiting for hardware access" log messages when
the interface is down, we should just disallow accessing the
device through debugfs when it is down.

The EEPROM reading/parsing code is all mixed in
the driver today, and the EEPROM is parsed only
when we access data from it. This is problematic
because the NVM needs to be parsed and that is
independent of reading it. Also, the NVM format
for new devices will be different and probably
require a new parser.
Therefore refactor the reading and parsing and
create two independent components. Reading the
EEPROM requires direct hardware accesses and
therefore access to the transport, but parsing
is independent and can be done on an NVM blob.

inside iwlwifi, move the current one into a
subdirectory to more cleanly separate the
code. While at it, rename all the files.
