drivers/soc/qualcomm/smem.c: In function ‘qcom_smem_alloc_private’:
drivers/soc/qualcomm/smem.c:391:2: warning: implicit declaration of
function ‘le32_add_cpu’ [-Wimplicit-function-declaration]
le32_add_cpu(&phdr->offset_free_uncached, alloc_size);
Please, add the missing definition to
./include/linux/byteorder/generic.h
or reference the prerequisite patch in the commit message.
Best regards
