ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl
commit 358040e3807754944dbddf948a23c6d914297ed7 upstream.
The update of rate_num/den and msbits were factored out to
fixup_unreferenced_params() function to be called explicitly after the
hw_refine or hw_params procedure. It's called from
snd_pcm_hw_refine_user(), but it's forgotten in the PCM compat ioctl.
This ended up with the incomplete rate_num/den and msbits parameters
when 32bit compat ioctl is used.
This patch adds the missing call in snd_pcm_ioctl_hw_params_compat().
