The main rt5514 driver optionally calls into the SPI back-end to load the firmware. This causes a link error when one driver selects rt5514 as built-in and another driver selects rt5514-spi as a loadable module:

sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put': rt5514.c:(.text+0xac8): undefined reference to `rt5514_spi_burst_write'

As a workaround, this adds another silent symbol, to force rt5514-spi to be built-in for that configuration. I'm not overly happy with that solution, but couldn't come up with anything better. Using 'IS_REACHABLE()' would break the case that relies on the loadable module, and all other ideas would result in more complexity.

The patch

ASoC: rt5514: mark PM functions as __maybe_unused

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark

From: Arnd Bergmann arnd@arndb.de Date: Fri, 10 Nov 2017 15:54:42 +0100 Subject: [PATCH] ASoC: rt5514: mark PM functions as __maybe_unused

The new functions are only used when CONFIG_PM is enabled, leading to a harmless warning:

sound/soc/codecs/rt5514-spi.c:474:12: error: 'rt5514_resume' defined but not used [-Werror=unused-function] sound/soc/codecs/rt5514-spi.c:464:12: error: 'rt5514_suspend' defined but not used [-Werror=unused-function]

This marks them as __maybe_unused to make the build silent again.
