Thanks, Mauro [PATCH v2] sound, media: allow building ISA drivers it with COMPILE_TEST All sound drivers that don't depend on PNP can be safelly build with COMPILE_TEST, as ISA provides function stubs to be used for such purposes. As a side effect, with this change, the radio-miropcm20 can now be built outside i386 with COMPILE_TEST. It should be noticed that ISAPNP currently depends on ISA. So, on drivers that depend on it, we need to add an explicit dependency on ISA, at least until another patch removes it. Signed-off-by: Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxxxxx> --- v2: only patch description changed, with the addition of a note about ISA explicit dependency on 3 drivers. diff --git a/drivers/media/radio/Kconfig b/drivers/media/radio/Kconfig index d363726e9eb1..8fa403c7149e 100644 --- a/drivers/media/radio/Kconfig +++ b/drivers/media/radio/Kconfig @@ -372,7 +372,8 @@ config RADIO_GEMTEK_PROBE config RADIO_MIROPCM20 tristate "miroSOUND PCM20 radio" - depends on ISA && ISA_DMA_API && VIDEO_V4L2 && SND + depends on ISA || COMPILE_TEST + depends on ISA_DMA_API && VIDEO_V4L2 && SND select SND_ISA select SND_MIRO ---help--- diff --git a/sound/isa/Kconfig b/sound/isa/Kconfig index cb54d9c0a77f..d2a6cdd0395c 100644 --- a/sound/isa/Kconfig +++ b/sound/isa/Kconfig @@ -20,7 +20,8 @@ config SND_SB16_DSP menuconfig SND_ISA bool "ISA sound devices" - depends on ISA && ISA_DMA_API + depends on ISA || COMPILE_TEST + depends on ISA_DMA_API default y help Support for sound devices connected via the ISA bus. @@ -38,7 +39,7 @@ config SND_ADLIB config SND_AD1816A tristate "Analog Devices SoundPort AD1816A" - depends on PNP + depends on PNP && ISA select ISAPNP select SND_OPL3_LIB select SND_MPU401_UART @@ -66,7 +67,7 @@ config SND_AD1848 config SND_ALS100 tristate "Diamond Tech.
