Hey,
So, the title of the patch is:
"iio: adc: ad7766: Change alignment to match paranthesis"
However, the patch is changing more files:
.../bindings/iio/adc/nuvoton,npcm-adc.txt | 11 -
.../iio/chemical/plantower,pms7003.txt | 20 ++
.../devicetree/bindings/vendor-prefixes.txt | 1 +
drivers/iio/adc/ad7766.c | 22 +-
drivers/iio/chemical/Kconfig | 10 +
drivers/iio/chemical/Makefile | 1 +
drivers/iio/chemical/pms7003.c | 340 ++++++++++++++++++
drivers/iio/chemical/sps30.c | 3 +
For one part, you are also adding a driver (pms7003.c).
The idea is that the title of the patch should summarize what the
patch is doing.
In this case, it's not clear.
It looks to me that the patch was generated incorrectly via a git command.
So, maybe try to regenerate the patch with just the ad7766 driver changes.
Thanks
Alex
