Subject: [PATCH 0/8] riscv: resolve most warnings from sparse

Resolve most warnings from the 'sparse' static analysis tool for the
arch/riscv codebase.  This makes life easier for us as maintainers,
and makes it easier for developers to use static analysis tools on
their own changes.

This patch series incorporates some changes based on feedback from
Christoph Hellwig <hch@....de>.

Applies on the current riscv fixes branch that is based on v5.4-rc3.
