ALSA: 6fire - Fix signedness bug

2011-06-16T19:31:33+00:00

Fixed remaining issues of the signedness bug discovered by Dan Carpenter.
A check was remaining that tests if unsigned rt->rate is >= 0.
Changed that so that rt->rate now consistently uses ARRAY_SIZE(rates)
as invalid rate value and not -1.

ALSA: 6fire: Fix double-free bug in usb6fire_fw_ezusb_upload()

2011-06-14T05:27:26+00:00

We have a double-free bug in
sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload().
We already call release_firmware(fw) on line 258, so when we then do it
again after usb6fire_fw_ezusb_write() returns <0, we have a double-free.
Easily fixed by just removing the last call to release_firmware().

ALSA: 6fire: Don't leak firmware in error path

2011-06-02T17:56:31+00:00

One of the error paths in
sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload() neglects to free
the memory allocated for the firmware before returning, thus leaking the
memory.

ALSA: usb-audio: add new quirk type QUIRK_AUDIO_STANDARD_MIXER

2011-05-25T07:36:59+00:00

This quirk type will let the driver assume that there is a standard
mixer on a given interface, or that a specific mixer quirks will handle
the device.

ALSA: usb-audio: export snd_usb_feature_unit_ctl

2011-05-25T07:36:20+00:00

In order to allow quirks functions to hook up to the standard feature
unit op tables, this patch exports a pointer to the struct that is used
internally.

That way, all the code handling the control can be kept private, and
external code can reference the symbol to re-use it.

ALSA: usb-audio: rework add_control_to_empty()

2011-05-25T07:34:34+00:00

This patch renames add_control_to_empty() to snd_usb_mixer_add_control()
and exports it, so the quirks functions can make use of it.

Also, as "struct mixer_build" is private to mixer.c, rewrite the
function to take an argument of type "struct usb_mixer_interface"
instead.
