coccinelle: alloc_cast: drop removed allocatorsgrafted

- pci_alloc_consistent() and pci_zalloc_consistent() were removed by
  commit 7968778914e5
  ("PCI: Remove the deprecated "pci-dma-compat.h" API")

- kmem_alloc() was removed by commit f078d4ea8276
  ("xfs: convert kmem_alloc() to kmalloc()")

- kmem_zalloc() was removed by commit 10634530f7ba
  ("xfs: convert kmem_zalloc() to kzalloc()")

- kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit
  bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers")

So drop them from the rules.

No functional change.

+ * QUIRK_FLAG_SHARE_MEDIA_DEVICE:
+ *  Create Media Controller API entries
+ * QUIRK_FLAG_ALIGN_TRANSFER:
+ *  Allow alignment on audio sub-slot (channel samples) rather than on audio
+ *  slots (audio frames)
+ * QUIRK_TX_LENGTH:
+ *  Add length specifier to transfers
+ * QUIRK_FLAG_PLAYBACK_FIRST:
+ *  Start playback stream at first even in implement feedback mode
+ * QUIRK_FLAG_SKIP_CLOCK_SELECTOR:
+ *  Skip clock selector setup; the device may reset to invalid state
+ * QUIRK_FLAG_IGNORE_CLOCK_SOURCE:
+ *  Ignore errors from clock source search; i.e. hardcoded clock
+ * QUIRK_FLAG_ITF_USB_DSD_DAC:
+ *  Indicates the device is for ITF-USB DSD based DACs that need a vendor cmd
+ *  to switch between PCM and native DSD mode
+ * QUIRK_FLAG_CTL_MSG_DELAY:
+ *  Add a delay of 20ms at each control message handling
+ * QUIRK_FLAG_CTL_MSG_DELAY_1M:
+ *  Add a delay of 1-2ms at each control message handling
+ * QUIRK_FLAG_CTL_MSG_DELAY_5M:
+ *  Add a delay of 5-6ms at each control message handling
+ * QUIRK_FLAG_IFACE_DELAY:
+ *  Add a delay of 50ms at each interface setup
+ * QUIRK_FLAG_VALIDATE_RATES:
+ *  Perform sample rate validations at probe
+ * QUIRK_FLAG_DISABLE_AUTOSUSPEND:
+ *  Disable runtime PM autosuspend
+ * QUIRK_FLAG_IGNORE_CTL_ERROR:
+ *  Ignore errors for mixer access
+ * QUIRK_FLAG_DSD_RAW:
+ *  Support generic DSD raw U32_BE format
+ * QUIRK_FLAG_SET_IFACE_FIRST:
+ *  Set up the interface at first like UAC1
+ * QUIRK_FLAG_GENERIC_IMPLICIT_FB
+ *  Apply the generic implicit feedback sync mode (same as implicit_fb=1 option)
+ * QUIRK_FLAG_SKIP_IMPLICIT_FB
+ *  Don't apply implicit feedback sync mode
+ * QUIRK_FLAG_IFACE_SKIP_CLOSE
+ *  Don't closed interface during setting sample rate
+ * QUIRK_FLAG_FORCE_IFACE_RESET
+ *  Force an interface reset whenever stopping & restarting a stream
+ *  (e.g. after xrun)
+ * QUIRK_FLAG_FIXED_RATE
+ *  Do not set PCM rate (frequency) when only one rate is available
+ *  for the given endpoint.
+ * QUIRK_FLAG_MIC_RES_16 and QUIRK_FLAG_MIC_RES_384
+ *  Set the fixed resolution for Mic Capture Volume (mostly for webcams)
+ * QUIRK_FLAG_MIXER_PLAYBACK_MIN_MUTE
+ *  Set minimum volume control value as mute for devices where the lowest
+ *  playback value represents muted state instead of minimum audible volume
+ * QUIRK_FLAG_MIXER_CAPTURE_MIN_MUTE
+ *  Similar to QUIRK_FLAG_MIXER_PLAYBACK_MIN_MUTE, but for capture streams
+ * QUIRK_FLAG_SKIP_IFACE_SETUP
+ *  Skip the probe-time interface setup (usb_set_interface,
+ *  init_pitch, init_sample_rate); redundant with
+ *  snd_usb_endpoint_prepare() at stream-open time
+ * QUIRK_FLAG_MIXER_PLAYBACK_LINEAR_VOL
+ *  Set linear volume mapping for devices where the playback volume control
+ *  value is mapped to voltage (instead of dB) level linearly. In short:
+ *  x(raw) = (raw - raw_min) / (raw_max - raw_min); V(x) = k * x;
+ *  dB(x) = 20 * log10(x). Overrides QUIRK_FLAG_MIXER_PLAYBACK_MIN_MUTE
+ * QUIRK_FLAG_MIXER_CAPTURE_LINEAR_VOL
+ *  Similar to QUIRK_FLAG_MIXER_PLAYBACK_LINEAR_VOL, but for capture streams.
+ *  Overrides QUIRK_FLAG_MIXER_CAPTURE_MIN_MUTE
+ * QUIRK_FLAG_IFB_SILENCE_ON_EMPTY
+ *  In implicit feedback mode, when an entire capture URB returns with
+ *  all iso_frame_desc[i].status != 0 (bytes==0), do not silently return
+ *  from snd_usb_handle_sync_urb. Instead fall through and enqueue a
+ *  packet_info containing only size-0 packets, so the OUT ring keeps
+ *  moving (emits silence). Needed by Behringer Flow 8 (1397:050c).
+ * QUIRK_FLAG_MIXER_GET_CUR_BROKEN
+ *  Some mixers are sticky, which means that setting their current volume is a
+ *  no-op, and reading the current volume returns a constant value. The sticky
+ *  check disables these mixers to prevent confusing userspace. However, some
+ *  devices do have a tunable volume despite the reported current volume being
+ *  constant. As the sticky check can't distinguish between the two categories,
+ *  setting this flag tells that the device should fall into the second
+ *  category when GET_CUR returns a constant value, resulting in the sticky
+ *  check being non-fatal and only disabling GET_CUR instead of the whole mixer.
+ *  The current volume will then be provided by the internal cache that stores
+ *  the last set volume
+ * QUIRK_FLAG_PLAYBACK_URB_FIXUP
+ *  Set URB_ISO_ASAP flag for isochronous URBs and force nurbs to MAX_URBS.
+ *  This is needed for devices that exhibit boot-time audio stuttering due
+ *  to insufficient buffer depth combined with xHCI scheduling variability.
+ *  The larger buffer (MAX_URBS = 12, ~64ms) absorbs system scheduling
+ *  jitter during boot, while URB_ISO_ASAP ensures consistent xHCI scheduling.
+ * QUIRK_FLAG_ALWAYS_SET_RATE:
+ *  Issue SET_CUR for the sample rate even when the clock already reports the
+ *  requested rate.  A device advertising a single rate is otherwise never sent
+ *  the request at all, and some require it before streaming will start.
