[1/1] ASoC: tas2781: fixed compiling issue in m68k commit: 4c556d1ea5a771a91f946964d931b4974a6b917e All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

I know. I would still like to know what is the real cause. It might resurrect again, here or in other code. Gr{oetje,eeting}s, Geert

I had been troubled by this issue for several weeks. At first, I also think it would one of variables overflow, according to the compiling error message. However, after investigation, no result came out. In fact, compiler will report the line number where the variable overflow is, if there was risk on the variable overflow. Yet, this compiling error did not report any line number. Finally, I didn’t realize that it would be the code section overflow until that compiling error message magically disappeared, one day I removed some functions in the tas2781-fwlib.c. So, I began to simplify some functions in the code. > > > Signed-off-by: Shenghao Ding <shenghao-ding@ti.com> > > > > --- > > Changes in v1: > > - | Reported-by: kernel test robot <lkp@intel.com> > > | Closes: > > | https://lore.kernel.org/oe-kbuild-all/202309222048.RnSqEIK5-lkp@intel. > > | com/ > > > --- a/include/sound/tas2781-dsp.h > > +++ b/include/sound/tas2781-dsp.h > > @@ -77,6 +77,11 @@ struct tasdev_blk { > > unsigned int nr_cmds; > > unsigned int blk_size; > > unsigned int nr_subblocks; > > + /* fixed m68k compiling issue, storing the dev_idx as a member of block > > + * can reduce unnecessary timeand system resource comsumption of > > + * dev_idx mapping every time the block data writing to the dsp. > > + */ > > What is so special about "m68k" that it (1) fails there (and only there?
