Linux 5.18-rc3 (Linus Torvalds)

The third release candidate of 5.18 has prioritized to be released even on Easter Sunday, so we have it now. Everything looks quite normal, though email changes in devicetree files and sound card probing error handling fixes are making the diffstat a little bit odd.

Below is the diffstat of the releases in the last two years.

Note that the y-axis is in logarithm. I draw it using https://github.com/sjp38/relstat and https://github.com/sjp38/lazybox using below command:

$ relstat.py --since 2020-02-07 | ~/lazybox/gnuplot/plot.py \
    --data_fmt table --type labeled-lines --xtics_rotate -90 \
    --font "Times New Roman, 5pt" --ylog --pointsize 0.3

And, below is the diffstat of the -rc3 releases in the last two years.
