coding-style is a set of suggestions not dicta.

Many of the tests in checkpatch are not written out in
coding-style.

checkpatch does emit a message when used with --strict here:

The checkpatch test is:

# check for && or || at the start of a line
if ($rawline =~ /^\+\s*(&&|\|\|)/) {
CHK("LOGICAL_CONTINUATIONS",
"Logical continuations should be on the previous line\n" . $hereprev);
}

This message is not always emitted because code outside of
net, drivers/net, and drivers/staging does not use --strict
by default.
