ASoC: ab8500: Inform SoC Core that we have our own I/O arrangements
If codec->control_data is not populated SoC Core assumes we want to use regmap, which fails catastrophically, as we don't have one: Unable to handle kernel NULL pointer dereference at virtual address 00000080 pgd = c0004000 [00000080] *pgd=00000000 Internal error: Oops: 17 [#1] PREEMPT SMP ARM Modules linked in: CPU: 1 Not tainted (3.5.0-rc6-00884-g0b2419e-dirty #130) PC is at regmap_read+0x10/0x5c LR is at hw_read+0x80/0x90 pc : [<c01a91b8>] lr : [<c0216804>] psr: 60000013 Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
