ALSA: usb-audio: Don't resubmit pending URBs at MIDI error recovery

2014-12-16T17:39:07+00:00

commit 66139a48cee1530c91f37c145384b4ee7043f0b7 upstream.

In snd_usbmidi_error_timer(), the driver tries to resubmit MIDI input
URBs to reactivate the MIDI stream, but this causes the error when
some of URBs are still pending like:

 WARNING: CPU: 0 PID: 0 at ../drivers/usb/core/urb.c:339 usb_submit_urb+0x5f/0x70()

For avoiding these errors, check the pending URBs and skip
resubmitting such ones.

sound/radeon: Move 64-bit MSI quirk from arch to driver

2014-11-24T03:17:34+00:00

A number of radeon cards have a HW limitation causing them to be
unable to generate the full 64-bit of address bits for MSIs. This
breaks MSIs on some platforms such as POWER machines.

We used to have a powerpc specific quirk to address that on a
single card, but this doesn't scale very well, this is better
put under control of the drivers who know precisely what a given
HW revision can do.

We now have a generic quirk in the PCI code. We should set it
appropriately for all radeon's from the audio driver.

ALSA: hda - Limit 40bit DMA for AMD HDMI controllers

2014-11-24T03:02:53+00:00

AMD/ATI HDMI controller chip models, we already have a filter to lower
to 32bit DMA, but the rest are supposed to be working with 64bit
although the hardware doesn't really work with 63bit but only with 40
or 48bit DMA.  In this patch, we take 40bit DMA for safety for the
AMD/ATI controllers as the graphics drivers does.

ALSA: hda - One more HP machine needs to change mute led quirk

2014-11-21T09:58:08+00:00

The machine originally use the quirk ALC269_FIXUP_HP_GPIO_MIC1_LED,
but the LED doesn't work at all.

After this change, the machine will change to use
ALC269_FIXUP_HP_MUTE_LED_MIC1 through pin_fixup_tbl[], and the LED
works well.
