The HD-audio reconfig function got broken in the recent kernels, typically resulting in a failure like: snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present This is because of the code restructuring to move the PCM and control instantiation into the codec drive probe, by the commit [bcd96557: ALSA: hda - Build PCMs and controls at codec driver probe]. Although the commit above removed the calls of snd_hda_codec_build_pcms() and *_build_controls() at the controller driver probe, the similar calls in the reconfig were still left forgotten. This caused the conflicting and duplicated PCMs and controls. The fix is trivial: just remove these superfluous calls from reconfig_codec().

Now some codes and functionalities of hda_codec struct are moved to hdac_device struct. A few basic attributes like the codec address, vendor ID number, FG numbers, etc are moved to hdac_device, and they are accessed like codec->core.addr. The basic verb exec functions are moved, too.

A few basic codes for communicating over HD-audio bus are moved to struct hdac_bus now. It has only command and get_response ops in addition to the unsolicited event handling. Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.

The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

Use dev_err() and co for messages from HD-audio controller and codec drivers. The codec drivers are mostly bound with codec objects, so some helper macros, codec_err(), codec_info(), etc, are provided. They merely wrap the corresponding dev_xxx(). There are a few places still calling snd_printk() and its variants as they are called without the codec or device context. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

We have currently sysfs attributes for each hwdep, but basically these should belong to the codec itself, per se. Let's add them to the codec object while keeping them for hwdep as is for compatibility. While we are at it, split the sysfs-related stuff into a separate source file, hda_sysfs.c, and keep only the stuff necessary for hwdep in hda_hwdep.c. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

As the HD-audio is treated individually in each codec driver, it's more convenient to assign an own struct device to each codec object. Then we'll be able to use dev_err() more easily for each codec, for example. For achieving it, this patch just creates an object "hdaudioCxDy". It belongs to sound class instead of creating a new bus, just for simplicity, at this stage. No pm ops is implemented in the device struct level but currently it's merely a container. The PCM and hwdep devices are now children of this codec device. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Instead of calling each time device_create_file(), create the groups of sysfs attribute files at once in a normal way. Add a new helper function, snd_get_device(), to return the associated device object, so that we can handle the sysfs addition locally. Since the sysfs file addition is done differently now, snd_add_device_sysfs_file() helper function is removed. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

In the ugly real world, there area really broken devices that don't set codec SSID correctly. In such a case, the ID can be random, thus the patching won't work reliably.

Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space".
