Why can't you just do this: if (ssi_private->use_dual_fifo) { write_ssi_mask(&ssi->srcr, 0, CCSR_SSI_SRCR_RFEN1); write_ssi_mask(&ssi->stcr, 0, CCSR_SSI_STCR_TFEN1); write_ssi_mask(&ssi->scr, 0, CCSR_SSI_SCR_TCH_EN); } -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
