Subject: [PATCH] dwc_otg: Enable the hack for Split Interrupt transactions by
default
dwc_otg.fiq_fsm_mask=0xF has long been a suggestion for users with audio stutters or other USB bandwidth issues.
So far we are aware of many success stories but no failure caused by this setting.
Make it a default to learn more.
