I tried this, but due to the fact that the line has to be right-aligned to
column 80 we will still see a whitespace difference due to the length diff of
the name-related argument.

tried to remove it and

  CC [M]  mprls0025pa_i2c.o
mprls0025pa.h:89:63: error: 'IIO_DMA_MINALIGN' undeclared here (not in a function); did you mean 'ARCH_DMA_MINALIGN'?
   89 |         u8          buffer[MPR_MEASUREMENT_RD_SIZE] __aligned(IIO_DMA_MINALIGN);

I guess it makes more sense to move it to the .h file, where buffer[] is defined.

everything else will be fixed as per your feedback.

thanks,
peter
