2016-04-06ALSA: intel8x0: Drop superfluous VM checksTakashi Iwai1-17/+3
intel8x0 driver has the inside_vm check for skipping a buggy hardware workaround in the PCM pointer callback in the commit [228cf79376f1: ALSA: intel8x0: Improve performance in virtual environment]. This was originally applied to all devices on known VMs, but the code was switched to use the PCI ID matching for applying to only known devices (KVM and Parallels), in order to avoid applying wrongly to VT-d and other such cases, in the commit [7fb4f392bd27: ALSA: intel8x0: improve virtual environment detection]. Meanwhile, the original VM check was kept even after switching to the PCI ID matching. It was partly because we weren't 100% sure whether we had covered all well, and partly because this would help identifying the issue once when a user of another VM hit the same problem or a regression. Currently the VM check is used only for showing the kernel message that the VM-optimization isn't applied, and the VM check itself doesn't change the actual driver behavior at all. Despite the relatively safe driver behavior, the code caught attention of developers badly and brought many confusion / misunderstanding. Since we've got neither regression nor enhancement report for other VMs for five years long, it's likely safe to drop this superfluous VM check now. The module option is still kept, so if a user still needs to adjust, it can be applied as was. Acked-by: Konstantin Ozerkov <kozerkov@parallels.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-05-29ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at removeTakashi Iwai1-1/+0
As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-25ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai1-4/+6
Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.

2012-01-13module_param: avoid bool abuse, add bint for special cases.Rusty Russell1-2/+2
For historical reasons, we allow module_param(bool) to take an int (or an unsigned int). That's going away. A few drivers really want an int: they set it to -1 and a parameter will set it to 0 or 1. This sucks: reading them from sysfs will give 'Y' for both -1 and 1, but if we change it to an int, then the users might be broken (if they did "param" instead of "param=1"). Use a new 'bint' parser for them. (ntfs has a different problem: it needs an int for debug_msgs because it's also exposed via sysctl.)
