      ALSA: hda/realtek - Add shutup hint · c7273bd6
      Takashi Iwai 提交于
      The pin shutup callback seems working well on some devices while it
      does harm on some other devices; e.g. Lenovo laptops show often the
      noises at (runtime) PM with the pin shutup enabled.
      
      Currently, the only way to disable the pin shutup is to hard-code
        spec->shutup = alc_no_shutup;
      in the fixup, and this makes the debugging harder for normal users.
      For allowing users to test the similar effect without recompiling the
      kernel, this patch adds a new hint string "shutup".  It's a boolean
      value, and by passing false to this, user can turn off the pin shutup
      call.
      
      For example, to turn off the shutup on Lenovo P50, create a "firmware
      patch" file (e.g. /lib/firmware/alsa/lenovo-p50) containing the
      following lines:
      
        [codec]
        0x10ec0298 0x17aa222e 0
      
        [hint]
        shutup = no
      
      and pass the file via patch option of snd-hda-intel module
      (e.g. patch=alsa/lenovo-p50).

      treewide: Use array_size() in vmalloc() · 42bc47b3
      Kees Cook 提交于
      The vmalloc() function has no 2-factor argument form, so multiplication
      factors need to be wrapped in array_size(). This patch replaces cases of:
      
              vmalloc(a * b)
      
      with:
              vmalloc(array_size(a, b))
      
      as well as handling cases of:
      
              vmalloc(a * b * c)
      
      with:
      
              vmalloc(array3_size(a, b, c))
      
      This does, however, attempt to ignore constant size factors like:
      
              vmalloc(4 * 1024)
      
      though any constants defined via macros get caught up in the conversion.
      
      Any factors with a sizeof() of "unsigned char", "char", and "u8" were
      dropped, since they're redundant.
      
      The Coccinelle script used for this was:

      treewide: kzalloc() -> kcalloc() · 6396bb22
      Kees Cook 提交于
      The kzalloc() function has a 2-factor argument form, kcalloc(). This
      patch replaces cases of:
      
              kzalloc(a * b, gfp)
      
      with:
              kcalloc(a * b, gfp)
      
      as well as handling cases of:
      
              kzalloc(a * b * c, gfp)
      
      with:
      
              kzalloc(array3_size(a, b, c), gfp)
      
      as it's slightly less ugly than:
      
              kzalloc_array(array_size(a, b), c, gfp)
      
      This does, however, attempt to ignore constant size factors like:
      
              kzalloc(4 * 1024, gfp)
      
      though any constants defined via macros get caught up in the conversion.

      treewide: kmalloc() -> kmalloc_array() · 6da2ec56
      Kees Cook 提交于
      The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
      patch replaces cases of:
      
              kmalloc(a * b, gfp)
      
      with:
              kmalloc_array(a * b, gfp)
      
      as well as handling cases of:
      
              kmalloc(a * b * c, gfp)
      
      with:
      
              kmalloc(array3_size(a, b, c), gfp)
      
      as it's slightly less ugly than:
      
              kmalloc_array(array_size(a, b), c, gfp)
      
      This does, however, attempt to ignore constant size factors like:
      
              kmalloc(4 * 1024, gfp)
      
      though any constants defined via macros get caught up in the conversion.
      
      Any factors with a sizeof() of "unsigned char", "char", and "u8" were
      dropped, since they're redundant.
      
      The tools/ directory was manually excluded, since it has its own
      implementation of kmalloc().
      
      The Coccinelle script used for this was:

      ALSA: hda - Fix runtime PM · 009f8c90
      Lukas Wunner 提交于
      Before commit 3b5b899c ("ALSA: hda: Make use of core codec functions
      to sync power state"), hda_set_power_state() returned the response to
      the Get Power State verb, a 32-bit unsigned integer whose expected value
      is 0x233 after transitioning a codec to D3, and 0x0 after transitioning
      it to D0.
      
      The response value is significant because hda_codec_runtime_suspend()
      does not clear the codec's bit in the codec_powered bitmask unless the
      AC_PWRST_CLK_STOP_OK bit (0x200) is set in the response value.  That in
      turn prevents the HDA controller from runtime suspending because
      azx_runtime_idle() checks that the codec_powered bitmask is zero.
      
      Since commit 3b5b899c, hda_set_power_state() only returns 0x0 or
      0x1, thereby breaking runtime PM for any HDA controller.  That's because
      an inline function introduced by the commit returns a bool instead of a
      32-bit unsigned int.  The change was likely erroneous and resulted from
      copying and pasting snd_hda_check_power_state(), which is immediately
      preceding the newly introduced inline function.  Fix it.

      ALSA: echoaudio: Drop superfluous macro · afe5da3e
      Takashi Iwai 提交于
      Drop pci_device() macro that just leads to chip->pci->dev, and pass it
      directly to request_firmware().  It was introduced for allowing the
      external alsa-driver kernel module builds.  Since it was discontinued
      years ago, we should clean it up now.

      ALSA: hda/ca0132: fix array_size.cocci warnings · c5f13d75
      Fengguang Wu 提交于
      sound/pci/hda/patch_ca0132.c:5062:50-51: WARNING: Use ARRAY_SIZE
      sound/pci/hda/patch_ca0132.c:5092:50-51: WARNING: Use ARRAY_SIZE
      
       Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element
      
      Semantic patch information:
       This makes an effort to find cases where ARRAY_SIZE can be used such as
       where there is a division of sizeof the array by the sizeof its first
       element or by any indexed element or the element type. It replaces the
       division of the two sizeofs by ARRAY_SIZE.
