The default_trigger fields of struct gpio_led and thus struct led_classdev
are pretty much always assigned from a string literal, which means the
string can't be modified. Which is fine, since there is no reason to
modify the string and in fact it never is.
But they should be marked const to prevent such code from being added, to
prevent warnings if -Wwrite-strings is used and when assigned from a
constant string other than a string literal (which produces a warning under
current kernel compiler flags), and for general good coding practices.

Reposting this again. It still applies to powerpc-next as of Aug 28 and I
don't think anyone had any problems with it.
