[ Upstream commit 56beedc88405fd8022edfd1c2e63d1bc6c95efcb ]
Apollo Lake seems to also suffer from IRQ timing issues. After being up for ~4 minutes, a Pentium N4200 system ends up falling back to workqueue-based IRQ handling:
[ 208.019906] snd_hda_intel 0000:00:0e.0: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
Unfortunately, the Baytrail and Braswell workaround value of 32 samples isn't enough to fix the issue here. Default to 64 samples.
