Subject: ublk: remove unused cmd argument to ublk_dispatch_req()
X-Git-Tag: v6.15-rc1~29^2~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dfbce8b798fb848a42706e2e544b78b3db22aaae;p=thirdparty%2Fkernel%2Flinux.git

ublk: remove unused cmd argument to ublk_dispatch_req()

ublk_dispatch_req() never uses its struct io_uring_cmd *cmd argument.
Drop it so callers don't have to pass a value.
