Fix sparse warning:
sound/usb/qcom/qc_audio_offload.c:943:27: sparse: incorrect type in argument 2
expected unsigned int val but got snd_pcm_format_t.
Explicitly cast pcm_format to unsigned int for snd_mask_leave().
Fixes: 326bbc348298 ("ALSA: usb-audio: qcom: Introduce QC USB SND offloading support")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202604062109.Oxi8JjWW-lkp@intel.com/

I believe you need __force prefix for cast, as it's strong-typed.
