      ALSA: Remove memory reservation code from memalloc helper · 47d98c02
      Takashi Iwai 提交于
      Nowadays we have CMA for obtaining the contiguous memory pages
      efficiently.  Let's kill the old kludge for reserving the memory pages
      for large buffers.  It was rarely useful (only for preserving pages
      among module reloading or a little help by an early boot scripting),
      used only by a couple of drivers, and yet it gives too much ugliness
      than its benefit.

      ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove · 20a24225
      Takashi Iwai 提交于
      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.

      [media] tea575x-tuner: update to latest V4L2 framework requirements · d4ecc83b
      Hans Verkuil 提交于
      The tea575x-tuner module has been updated to use the latest V4L2 framework
      functionality. This also required changes in the drivers that rely on it.
      
      The tea575x changes are:
      
      - The drivers must provide a v4l2_device struct to the tea module.
      - The radio_nr module parameter must be part of the actual radio driver,
        and not of the tea module.
      - Changed the frequency range to the normal 76-108 MHz range instead of
        50-150.
      - Add hardware frequency seek support.
      - Fix broken rxsubchans/audmode handling.
      - The application can now select between stereo and mono.
      - Support polling for control events.
      - Add V4L2 priority handling.
      
      And radio-sf16fmr2.c now uses the isa bus kernel framework.

      ALSA: mpu401: clean up interrupt specification · dba8b469
      Clemens Ladisch 提交于
      The semantics of snd_mpu401_uart_new()'s interrupt parameters are
      somewhat counterintuitive:  To prevent the function from allocating its
      own interrupt, either the irq number must be invalid, or the irq_flags
      parameter must be zero.  At the same time, the irq parameter being
      invalid specifies that the mpu401 code has to work without an interrupt
      allocated by the caller.  This implies that, if there is an interrupt
      and it is allocated by the caller, the irq parameter must be set to
      a valid-looking number which then isn't actually used.
      
      With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
      which forces us to handle the parameters differently.
      
      This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
      device interrupt is handled by the caller, and makes the allocation of
      the interrupt to depend only on the irq parameter.  As suggested by
      Takashi, the irq_flags parameter was dropped because, when used, it had
      the constant value IRQF_DISABLED.

      ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/* · 934c2b6d
      Takashi Iwai 提交于
      The name argument of request_irq() appears in /proc/interrupts, and
      it's quite ugly when the name entry contains a space or special letters.
      In general, it's simpler and more readable when the module name appears
      there, so let's replace all entries with KBUILD_MODNAME.

      ALSA: Use KBUILD_MODNAME for pci_driver.name entries · 3733e424
      Takashi Iwai 提交于
      The convention for pci_driver.name entry in kernel drivers seem to be
      the module name or equivalent ones.  But, so far, almost all PCI sound
      drivers use more verbose name like "ABC Xyz (12)", and these are fairly
      confusing when appearing as a file name.
      
      This patch converts the all pci_driver.name entries in sound/pci/* to
      use KBUILD_MODNAME for more unified appearance.

      ALSA: snd-es1968: Make hardware volume buttons an input device (rev2) · 5a5e02e5
      Hans de Goede 提交于
      The hardware volume handling code in essence just detects key presses, and
      then does some hardcoded modification of the master volume based on which key
      is pressed.
      
      Clearly the right thing to do here is just report these keypresses to
      userspace and let userspace decide what to with them.
      
      This patch adds a Kconfig option which when enabled reports the volume
      buttons as keypresses using an input device. When enabled this option
      also gets rid of the ugly direct ac97 writes from the tasklet, the ac97lock
      and the need for using a tasklet in general.

      es1968: fix sleep-while-holding-lock bug · 4b47c971
      Arjan van de Ven 提交于
      snd_es1968_ac97_read() calls snd_es1968_ac97_wait() first outside a locked
      area, and later, while holding a lock.
      
      snd_es1968_ac97_wait() has a polling loop with a cond_resched() inside it..
      which sleeps, so the second call is invalid.
      
      This patch adds a version of the wait function that just pure polls.  While
      this is not very elegant in principle, it's very likely the easiest thing to
      do here, we already checked if the chip was ready (while yielding) just
      before, so it is very unlikely to take a long time here.

      This header file exists only for some hacks to adapt alsa-driver
