Some kernel configurations can cause following build error:
sound/soc/intel/sst-baytrail-ipc.c: In function ‘sst_byt_get_dsp_position’: sound/soc/intel/sst-baytrail-ipc.c:744:2: error: implicit declaration of function ‘memcpy_fromio’ [-Werror=implicit-function-declaration] memcpy_fromio(&fw_tstamp, ^ cc1: some warnings being treated as errors
Fix this by including <linux/io.h> explicitly.
Reported-by: kbuild test robot fengguang.wu@intel.com Signed-off-by: Jarkko Nikula jarkko.nikula@linux.intel.com --- v2: including <linux/io.h> instead of <asm/io.h>. Thanks to Takashi Iwai for noticing (checkpatch.pl tells it too).
Also sst-dsp., sst-baytrail-dsp.c and sst-haswell-dsp.c are using memcpy_fromio/_toio but there <asm/io.h> seems to come via <linux/dma-mapping.h> or <linux/io.h> so I didn't touch them. --- sound/soc/intel/sst-baytrail-ipc.c | 1 + 1 file changed, 1 insertion(+)
