From: Arnd Bergmann <arnd@arndb.de> The ipi handler here tries hard to maintain const-ness of its argument, but by doing that causes a warning about function type casts:I worked on the same issue, but in instead of removing the const, I tried to constify everything: https://patchwork.linuxtv.org/project/linux-media/patch/20240226-fix-clang-warnings-v2-3-fa1bc931d17e@chromium.org/
I had almost the same patch originally but ended up not sending
it because I could not figure out what to do about
typedef int (*rpmsg_rx_cb_t)(struct rpmsg_device *, void *, int, void *, u32);
which is a generic part of rpmsg that takes a non-const pointer
and gets called by mtk_rpmsg_ipi_handler(), which would now
get a const pointer.
