From 409c69be433b819c924a8d1c457a835bc6d51700 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 10 Dec 2016 11:51:11 +0200 Subject: ASoC: samsung: Remove tests of member address The driver was checking for non-NULL address of struct's members: - s3c_audio_pdata->type (union), - s3c_audio_pdata->type.i2s (embedded struct). This is pointless as these will be always non-NULL. The 's3c_audio_pdata' is always initialized in static memory so it will be zeroed. Additionally the 'type' member was an union with only one member. It is safe to reorganize the structures to get rid of useless union and checks for addresses to fix the coccinelle warning: >> sound/soc/samsung/i2s.c:1270:2-4: ERROR: test of a variable/field address Reported-by: kbuild test robot Signed-off-by: Krzysztof Kozlowski Reviewed-by: Bartlomiej Zolnierkiewicz Signed-off-by: Mark Brown --- include/linux/platform_data/asoc-s3c.h | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'include') diff --git a/include/linux/platform_data/asoc-s3c.h b/include/linux/platform_data/asoc-s3c.h index 15bf56ee8af7..90641a5daaf0 100644 --- a/include/linux/platform_data/asoc-s3c.h +++ b/include/linux/platform_data/asoc-s3c.h @@ -18,7 +18,7 @@ extern void s3c64xx_ac97_setup_gpio(int); -struct samsung_i2s { +struct samsung_i2s_type { /* If the Primary DAI has 5.1 Channels */ #define QUIRK_PRI_6CHAN (1 << 0) /* If the I2S block has a Stereo Overlay Channel */ @@ -47,7 +47,5 @@ struct s3c_audio_pdata { void *dma_capture; void *dma_play_sec; void *dma_capture_mic; - union { - struct samsung_i2s i2s; - } type; + struct samsung_i2s_type type; }; -- cgit v1.2.3-71-gd317 From e8314d7d53c8b050aac2828a5de5f28a997b468b Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Tue, 6 Dec 2016 20:22:36 +0100 Subject: misc: atmel-ssc: register as sound DAI if #sound-dai-cells is present The SSC is currently not usable with the ASoC simple-audio-card, as every SSC audio user has to build a platform driver that may do as little as calling atmel_ssc_set_audio/atmel_ssc_put_audio (which allocates the SSC and registers a DAI with the ASoC subsystem). So, have that happen automatically, if the #sound-dai-cells property is present in devicetree, which it has to be anyway for simple audio card to work.

This patch adds an API to allow the DMI name to be used in the sound card long name, thereby helping userspace load the correct UCM configuration. Usually machine drivers uses their own name as the sound card name (short name), and leave the long name and driver name blank. This API will use the DMI info like vendor, product and board to make up the card long name. If the machine driver has already explicitly set the long name, this API will do nothing. This patch also allows for further differentiation as many devices that share the same DMI name i.e. Minnowboards, UP boards may be configured with different codecs or firmwares. The API supports flavoring the DMI name into the card longname to provide the extra differentiation required for these devices. For Use Case Manager (UCM) in the user space, changing card long name by this API is backward compatible, since the card name does not change. For a given sound card, even if there is no device-specific UCM configuration file that uses the card long name, UCM will fall back to load the default configuration file that uses the card name.
