The patch titled
ALSA: intel8x0 - Fix Oops in kdump crash kernel
has been removed from the -mm tree. Its filename was
alsa-intel8x0-fix-oops-in-crash-kernel.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ALSA: intel8x0 - Fix Oops in kdump crash kernel
From: Takashi Iwai <tiwai@xxxxxxx>
When intel8x0 driver is loaded in the crash kernel, it gets Oops
occasionally. This is because the irq handler gets called before the
proper hardware initialization. Now defer it after
snd_intel8x0_chip_init().
