[alsa-devel] ASoC: wm8962: NULL pdata pointer
by Shawn Guo 04 Jul '13

04 Jul '13

Mark, I'm running next-20130703 and seeing the following NULL pointer bug. Unable to handle kernel NULL pointer dereference at virtual address 00000004 pgd = 80004000 [00000004] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-next-20130703 #6 task: bf870000 ti: bf874000 task.ti: bf874000 PC is at wm8962_probe+0x140/0x6b4 ... It seems to me that it's caused by a merge error in 384b834. And the change below can remove the problem.

[alsa-devel] [PATCH] mfd: arizona: Move regulator disable to after marking cache only
by Charles Keepax 03 Jul '13

If we disable DCVDD before we mark the cache as cache only, we might attempt to write to the chip whilst it is powered down and lose a write.
