2018-01-12ASoC: rt5645: add fallback case for jack detection supportPierre-Louis Bossart
Commit 78f5605c0329 ("ASoC: rt5645: cleanup DMI matching code") did a lot of useful cleanups. This patch adds a default case to enable jack detection if there is no pdata, device property or quirk. The chosen jd-mode3 is the most common and should limit the addition of new DMI-based quirks. Existing DMI quirks which only set this mode are left as is and not removed.

2018-01-11ASoC: stm32: select IIO_BUFFERArnd Bergmann
The new stm32_adfsdm driver has incomplete dependencies as shown by Kconfig: warning: (SND_SOC_STM32_DFSDM && LMP91000) selects IIO_BUFFER_CB which has unmet direct dependencies (IIO && IIO_BUFFER) sound/soc/stm/stm32_adfsdm.o: In function `stm32_adfsdm_trigger': stm32_adfsdm.c:(.text+0x8c): undefined reference to `stm32_dfsdm_get_buff_cb' stm32_adfsdm.c:(.text+0x9c): undefined reference to `stm32_dfsdm_release_buff_cb' This makes the dependency on SND_SOC_STM32_DFSDM unconditional, so we can always resolve the stm32_dfsdm_get_buff_cb/stm32_dfsdm_release_buff_cb symbols and get the implied IIO_BUFFER dependency. compile-testing on other platforms is still possible as long as that IIO driver is there.
