I think you need to modfiy the order and this and following change. With last patch applied and this not present, you would break if someone tries to read debugfs file as these adresses are NULL, so add these values first and then the usage :)
sst_dsp_mailbox_init(sst, (BXT_ADSP_SRAM0_BASE + SKL_ADSP_W0_STAT_SZ), SKL_ADSP_W0_UP_SZ, BXT_ADSP_SRAM1_BASE, SKL_ADSP_W1_SZ); -- 2.13.0
