Subject[PATCH] ASoC: pxa: don't select SSP for COMPILE_TESTing
Message-ID<ubNLH-74u-3@gated-at.bofh.it>
When the audio driver selects CONFIG_PXA_SSP to be a loadable
module on a platform other than PXA, and the PXA SPI driver
is built-in, we get a link error in the SPI driver:

drivers/spi/spi-pxa2xx.o: In function `pxa2xx_spi_remove':
spi-pxa2xx.c:(.text+0x5f0): undefined reference to `pxa_ssp_free'
drivers/spi/spi-pxa2xx.o: In function `pxa2xx_spi_probe':
spi-pxa2xx.c:(.text+0xeac): undefined reference to `pxa_ssp_request'
spi-pxa2xx.c:(.text+0x1468): undefined reference to `pxa_ssp_free'
spi-pxa2xx.c:(.text+0x15bc): undefined reference to `pxa_ssp_free'

Why doesn't this cause problems on PXA?

On PXA, we 'make' descends into arch/arm/plat-pxa/, where ssp.o
is located. On other ARM platforms (I guess except for MMP),
PLAT_PXA is not set, and on non-ARM architectures, we can't
get there anyway.

Still missing a few steps of reasoning here...

Sorry, I just realized that you were trying to point out the incomplete
changelog. I must have accidentally closed the editor while working on
it, and then sent it out today after getting no regressions.

I'll resend with a proper changelog.

While trying to write up a better changelog, I found that I had run into this
before and attempted a different fix, see
https://patchwork.kernel.org/patch/8879921/

The commit I referred to in "Fixes:" did not introduce a new problem at
all, but it appears to have made it more likely to run into this situation.

Sending a third patch now, again different.

Mark, let me know if you want something else instead.
