Subject: [RESEND PATCH] ASoC: atmel: fix atmel_ssc_set_audio link failure
Date: Thu, 30 Jan 2020 15:05:45 +0200 [thread overview]
Message-ID: <20200130130545.31148-1-codrin.ciubotariu@microchip.com> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The ssc audio driver can call into both pdc and dma backends. With the
latest rework, the logic to do this in a safe way avoiding link errors
was removed, bringing back link errors that were fixed long ago in commit
061981ff8cc8 ("ASoC: atmel: properly select dma driver state") such as
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio':
atmel_ssc_dai.c:(.text+0xac): undefined reference to `atmel_pcm_pdc_platform_register'
Fix it this time using Makefile hacks and a comment to prevent this
from accidentally getting removed again rather than Kconfig hacks.
Fixes: 18291410557f ("ASoC: atmel: enable SOC_SSC_PDC and SOC_SSC_DMA in Kconfig")

Added my signed-off because I sent the patch, no other changes.
