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 }
regards,
dan carpenter
