So for now I have suppressed the error using the following patch (which I will keep in my fixes tree until some other fix is applied): From: Stephen Rothwell <s...@canb.auug.org.au> Date: Fri, 22 Jan 2016 13:24:57 +1100 Subject: [PATCH] next: suppress the building of all the sound codecs on PPC for now Signed-off-by: Stephen Rothwell <s...@canb.auug.org.au> --- sound/soc/codecs/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index 50693c867e71..ee5f36b9c787 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -13,6 +13,7 @@ menu "CODEC drivers" config SND_SOC_ALL_CODECS tristate "Build all ASoC CODEC drivers" depends on COMPILE_TEST + depends on !PPC select SND_SOC_88PM860X if MFD_88PM860X select SND_SOC_L3 select SND_SOC_AB8500_CODEC if ABX500_CORE -- 2.6.4 -- Cheers, Stephen Rothwell s...@canb.auug.org.au
