While backporting this patch to a vendor tree I noticed checkpatch criticising:
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
for the above line. Would you fixup an "int" into that line please, or
is that already too late?
Something like:
git checkout togreg
sed -i 's/unsigned status_reg;/unsigned int status_reg;/' drivers/iio/adc/ad_sigma_delta.c
git commit --fixup=132d44dc6966 drivers/iio/adc/ad_sigma_delta.c
git rebase -r --autosquash 132d44dc6966^
If it's already to late, I can prepare a proper patch for that.
Best regards
Uwe
