* ALSA: hda - Fix memory leaks in conexant jack arraysTakashi Iwai2011-02-021-1/+7
| | | | | | | | | | | | | | | The Conexant codec driver adds the jack arrays in init callback which may be called also in each PM resume. This results in the addition of new jack element at each time. The fix is to check whether the requested jack is already present in the array.

| * ALSA: HDA: cxt5066 - Use asus model for Asus U50F, select correct SPDIF outputAndy Robinson2011-01-241-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed the Asus A52J quirk to use the asus model instead of the hp_laptop model, which fixes the external mic input. Added an Asus U50F quirk to use the asus model. For the cxt5066 codecs, added checking of the digital output pins to determine which digital output nodes to use instead of always using node 0x21, since some systems have node 0x12 connected to a SPDIF out jack.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the multi-component patch the s3c24xx i2s driver was renamed from "s3c24xx-i2s" to "s3c24xx-iis", while the sound board drivers were not updated to reflect this change as well. As a result there is no match between the dai_link and the i2s driver and no sound card is instantiated. This patch fixes the problem by updating the sound board drivers to use "s3c24xx-iis" for the cpu_dai_name.

| * | ASoC: Fix codec device id format used by some dai_linksLars-Peter Clausen2011-01-256-8/+8

So for example for an I2C device which is connected to the adapter with the id 0 and has its address set to 0x1a the id part of the devices name would be "0-001a". Currently some sound board drivers have the id part the codec_name field of their dai_link structures set as if it had been created by a "%d-0x%x" format string. For example "0-0x1a" instead of "0-001a". As a result there is no match between the codec device and the dai_link and no sound card is instantiated. This patch fixes it.

I guess that what's needed to fix it is the trivial patch below, but I must admit that I have no idea about this code, so I may very well be wrong. Additionally, I have no way to actually test this, so all I know is that the below compiles.

Going over the code I cannot convince myself its correct: - holding a ref on the parent_ctx, doesn't avoid it being uncloned concurrently (as the comment says), so we can race with a free. - holding parent_ctx->mutex doesn't avoid the above free from taking place either, it would at best avoid parent_ctx from being freed. I.e. the warning is correct. To fix the bug, serialize against the unclone_ctx() call by extending the reach of the parent_ctx->lock.

According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to 2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is using such binutils. See: http://sourceware.org/bugzilla/show_bug.cgi?id=12327 The reason of the boot panic is that we have 'jiffies = jiffies_64;' in vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is warning saying jiffies is an absolute address and can't be relocatable. At runtime, jiffies will have virtual address 0.

Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB.
