When deploying SFQ/IFB here at work, I found the allot management was
pretty wrong in sfq, even changing allot from short to int...
We should init allot for each new flow, not using a previous value found
in slot.
Before patch, I saw bursts of several packets per flow, apparently
denying the default "quantum 1514" limit I had on my SFQ class.
class sfq 11:1 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 7p requeues 0
allot 11546
class sfq 11:46 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 1p requeues 0
allot -23873
class sfq 11:78 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 5p requeues 0
allot 11393
After patch, better fairness among each flow, allot limit being
respected, allot is positive :
class sfq 11:e parent 11:
(dropped 0, overlimits 0 requeues 86)
backlog 0b 3p requeues 86
allot 596
class sfq 11:94 parent 11:

Its possible for the call to read rx timeout from the hardware to fail,
in which case we end up with a bogus rx timeout value. Set a default one
when filling in the rc struct, and we'll just overwrite it later w/the
value from hardware, but if that read fails, we've at least got a sane
rx timeout value to work with (1000ms is the default value I've seen
returned on most if not all mceusb hardware).

As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

This makes several changes but they're in one function and sort of
related:
"buf" was leaked on error. The leak if we try to read an invalid
length is the main concern because it could be triggered over and
over.
If the copy_to_user() failed, then the original code returned the
number of bytes remaining. read() is supposed to be the opposite way,
where we return the number of bytes copied. I changed it to just return
-EFAULT on errors.
Also I changed the debug output from "-EFAULT" to just "<fail>" because
it isn't -EFAULT necessarily. And since we go though that path if the
length is invalid now, there was another debug print that I removed.

When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.

There are cases where we get an ending space, and our trailing timeout
space then gets sent right after it, which breaks repeat, at least for
lirc userspace decoding. Merge the two spaces by way of using
ir_raw_event_store_filter, set a timeout value, and we're back to good.

Something I failed to notice while testing the mceusb RLE buffer
decoding simplification patches was that we were getting an extra event
from the previously pressed key.
As was pointed out to me on irc by Maxim, this is actually due to using
ir_raw_event_store_with_filter without having set up a timeout value.
The hardware has a timeout value we're now reading and storing, which
properly enables the transition to idle in the raw event storage
process, and makes IR decode behave correctly w/o keybounce.
Also remove no-longer-used ir_raw_event struct from mceusb_dev struct
and add as-yet-unused enable flags for carrier reports and learning
mode, which I'll hopefully start wiring up sooner than later. While
looking into that, found evidence that 0x9f 0x15 responses are only
non-zero when the short-range learning sensor is used, so correct the
debug spew message, and then suppress it when using the standard
long-range sensor.

We were storing a bunch of spaces at the end of each signal, rather than
a single long space. The in-kernel decoders were actually okay with
this, but lirc isn't. As suggested by David Härdeman, switch to storing
samples using ir_raw_event_store_with_filter, which auto-merges the
consecutive space samples for us. This also allows us to bypass having
to store rawir samples in our device struct, further simplifying the
buffer parsing state machine. Both in-kernel decoders and lirc are happy
again with this change.
Also included in this patch is proper parsing of 0x9f 0x01 commands, the
removal of some magic number usage and some printk spew fixups.
