ASoC: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following warning: In file included from arch/x86/include/asm/uaccess.h:573, from include/linux/poll.h:14, from include/sound/pcm.h:29, from include/sound/ac97_codec.h:31, from sound/soc/soc-core.c:34: In function 'copy_from_user', inlined from 'codec_reg_write_file' at sound/soc/soc-core.c:252: arch/x86/include/asm/uaccess_64.h:65: warning: call to 'copy_from_user_overflow' declared with attribute warning: copy_from_user() buffer size is not provably correct presumably due to buf_size being signed causing GCC to fail to see that buf_size can't become negative.
