The Droids MuIn LCD operates like a serial remote terminal.
Data received are displayed directly on the LCD. This patch
fixes the kernel null pointer oops when it is plugged in.Add NO_DATA_INTERFACE quirk to tell the driver that "control"
and "data" interfaces are not separated for this device, which
prevents dereferencing a null pointer in the device probe code.Signed-off-by: Erik Slagter

The pbLua console port is known to not be a modem, so it is
unnecessary to be told this when it is plugged in.Add NOT_A_MODEM quirk to tell the driver that we know this already
and hence not to warn us, and mark the pbLua console port.Signed-off-by: Julian Calaby

This patch fixes an oops caused when during an unplug a device's table
of endpoints is zeroed before the driver is notified. A pointer to
the endpoint must be cached.this fixes a regression caused by commit

This implement support in cdc-acm for acm devices another popular OS can handle
- adds support for autodetection of devices that use one interface
- autodetection of endpoints
- add a quirk for surpressing a setting that OS doesn't use
- autoassume that quirk for single interface devicesSigned-off-by: Oliver Neukum

Add a mechanism to let the write queue drain naturally before
closing the TTY, rather than always losing that data. There
is a timeout, so it can't wait too long.Provide missing locking inside acm_wb_is_avail(); it matters
more now. Note, this presumes an earlier patch was applied,
removing a call to this routine where the lock was held.Slightly improved diagnostics on write URB completion, so we
can tell when a write URB gets killed and, if so, how much
data it wrote first ... and so that I/O path is normally
silent (and can't much change timings).Signed-off-by: David Brownell

The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!). This patch removes them:- The write_ready flag ... if an URB and buffer were found,
they can (and should!) always be used.- TX path acm_wb_is_used() ... used when the buffer was just
allocated, so that check is pointless.Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

the following patch uses 16 write urbs and a writsize of wMaxPacketSize
* 20. With this patch I get the maximum througput from my linux system
with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both)I also deleted the flag URB_NO_FSBR for the writeurbs, because this
makes my full speed devices significant slower.Signed-off-by: David Engraf

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
