Subject: kunit: take `kunit_assert` as `const`
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7466886b400b;p=linux.git

kunit: take `kunit_assert` as `const`

The `kunit_do_failed_assertion` function passes its
`struct kunit_assert` argument to `kunit_fail`. This one,
in turn, calls its `format` field passing the assert again
as a `const` pointer.

Therefore, the whole chain may be made `const`.
