Subject: [PATCH v4 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 fourth version drops some patches that were in the previous
versions, and restructures some of what was left. Much of this was
based on feedback from Christoph Hellwig <hch@....de>, Luc Van
Oostenryck <luc.vanoostenryck@...il.com>, and Greentime Hu
<greentime.hu@...ive.com>.
Applies on the current riscv fixes branch, which itself is based on
v5.4-rc5. Tested on RV32 QEMU, RV64 QEMU, and the SiFive HiFive
Unleashed board.
