Subject: io_uring/napi: Remove unnecessary s64 cast
X-Git-Tag: v6.11-rc1~232^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f7c696a56cc7d70515774a24057b473757ec6089;p=thirdparty%2Fkernel%2Flinux.git

io_uring/napi: Remove unnecessary s64 cast

Since the do_div() macro casts the divisor to u32 anyway, remove the
unnecessary s64 cast and fix the following Coccinelle/coccicheck
warning reported by do_div.cocci:

  WARNING: do_div() does a 64-by-32 division, please consider using div64_s64 instead
