[alsa-devel] ASoC: Intel: Add Haswell/Broadwell IPC

[Dan Carpenter]

Hello Liam Girdwood,

The patch 22981243589c: "ASoC: Intel: Add Haswell/Broadwell IPC" from
Feb 20, 2014, leads to the following imaginary static checker warning:

	sound/soc/intel/sst-haswell-ipc.c:898 hsw_irq_thread()
	warn: this is always true.

sound/soc/intel/sst-haswell-ipc.c
   895                  /* Handle Immediate reply from DSP Core */
   896                  handled = hsw_process_reply(hsw, ipcx);
                                  ^^^^^^^^^^^^^^^^^
Returns 1 on success/error and -EIO on error.

   897  
   898                  if (handled) {
   899                          /* clear DONE bit - tell DSP we have completed */
   900                          sst_dsp_shim_update_bits_unlocked(sst, SST_IPCX,
   901                                  SST_IPCX_DONE, 0);
   902  
   903                          /* unmask Done interrupt */
   904                          sst_dsp_shim_update_bits_unlocked(sst, SST_IMRX,
   905                                  SST_IMRX_DONE, 0);
   906                  }
