asus-laptop: Do not call HWRS on init

2013-03-06T03:24:26+00:00

commit cb7da022450cdaaebd33078b6b32fb7dd2aaf6db upstream.

Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module
initialisation is very slow on the Asus UL30A.  The HWRS method takes
about 12 seconds to run, and subsequent initialisation also seems to
be delayed.  Since we don't really need the result, don't bother
calling it on init.  Those who are curious can still get the result
through the 'infos' device attribute.

Update the comment about HWRS in show_infos().

speakup: lower default software speech rate

2013-03-06T03:24:26+00:00

commit cfd757010691eae4e17acc246f74e7622c3a2f05 upstream.

Speech synthesis beginners need a low speech rate, and trained people
want a high speech rate.  A medium speech rate is thus actually not a
good default for neither.  Since trained people will typically know how
to change the rate, better default for a low speech rate, which
beginners can grasp and learn how to increase it afterwards

This was agreed with users on the speakup mailing list.

usb: Add USB_QUIRK_RESET_RESUME for all Logitech UVC webcams

2013-03-06T03:24:26+00:00

commit e387ef5c47ddeaeaa3cbdc54424cdb7a28dae2c0 upstream.

Most Logitech UVC webcams (both early models that don't advertise UVC
compatibility and newer UVC-advertised devices) require the RESET_RESUME
quirk. Instead of listing each and every model, match the devices based
on the UVC interface information.

usb: Add quirk detection based on interface information

2013-03-06T03:24:25+00:00

commit 80da2e0df5af700518611b7d1cc4fc9945bcaf95 upstream.

When a whole class of devices (possibly from a specific vendor, or
across multiple vendors) require a quirk, explictly listing all devices
in the class make the quirks table unnecessarily large. Fix this by
allowing matching devices based on interface information.

8250: use correct value for PORT_BRCM_TRUMANAGE

2013-03-06T03:24:25+00:00

When backporting commit ebebd49a8eab ('8250/16?50: Add support for
Broadcom TruManage redirected serial port') I took the next
available port type number for PORT_BRCM_TRUMANAGE (22).

However, the 8250 port type numbers are exposed to userland through
the TIOC{G,S}SERIAL ioctls and so must remain stable.  Redefine
PORT_BRCM_TRUMANAGE as 25, matching mainline as of commit
85f024401bf807.

This leaves port types 22-24 within the valid range for 8250 but not
implemented there.  Change serial8250_verify_port() to specifically
reject these and change serial8250_type() to return "unknown" for them
(though I'm not sure why it would ever see them).

vhost: fix length for cross region descriptor

2013-03-06T03:24:25+00:00

commit bd97120fc3d1a11f3124c7c9ba1d91f51829eb85 upstream.

If a single descriptor crosses a region, the
second chunk length should be decremented
by size translated so far, instead it includes
the full descriptor length.

Avoid sysfs oops when an rc_dev's raw device is absent

2013-03-06T03:24:24+00:00

commit 720bb6436ff30fccad05cf5bdf961ea5b1f5686d upstream.

For some reason, when the lirc daemon learns that a usb remote control
has been unplugged, it wants to read the sysfs attributes of the
disappearing device. This is useful for uncovering transient
inconsistencies, but less so for keeping the system running when such
inconsistencies exist.

Under some circumstances (like every time I unplug my dvb stick from
my laptop), lirc catches an rc_dev whose raw event handler has been
removed (presumably by ir_raw_event_unregister), and proceeds to
interrogate the raw protocols supported by the NULL pointer.

This patch avoids the NULL dereference, and ignores the issue of how
this state of affairs came about in the first place.

Version 2 incorporates changes recommended by Mauro Carvalho Chehab
(-ENODEV instead of -EINVAL, and a signed-off-by).
