Clang 14 in an (essentially) defconfig loongarch64 build for next-20240327 reports [1]:
drivers/gpu/drm/qxl/qxl_ioctl.c:148:14: error: variable 'num_relocs' set but not used [-Werror,-Wunused-but-set-variable] The variable was originally used in the `out_free_bos` label, but commit 74d9a6335dce ("drm/qxl: Simplify cleaning qxl processing command") removed the use that happened in that label. Thus remove the unused variable. Fixes: 74d9a6335dce ("drm/qxl: Simplify cleaning qxl processing command") Closes: https://lore.kernel.org/lkml/CANiq72kqqQfUxLkHJYqeBAhpc6YcX7bfR96gmmbF=j8heoy...@mail.gmail.com/ [1] Signed-off-by: Miguel Ojeda <oj...@kernel.org> --- drivers/gpu/drm/qxl/qxl_ioctl.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/gpu/drm/qxl/qxl_ioctl.c b/drivers/gpu/drm/qxl/qxl_ioctl.c index dd0f834d881c..506ae1f5e099 100644 --- a/drivers/gpu/drm/qxl/qxl_ioctl.c +++ b/drivers/gpu/drm/qxl/qxl_ioctl.c @@ -145,7 +145,7 @@ static int qxl_process_single_command(struct qxl_device *qdev, struct qxl_release *release; struct qxl_bo *cmd_bo; void *fb_cmd; - int i, ret, num_relocs; + int i, ret; int unwritten; switch (cmd->type) { @@ -200,7 +200,6 @@ static int qxl_process_single_command(struct qxl_device *qdev, } /* fill out reloc info structs */ - num_relocs = 0; for (i = 0; i < cmd->relocs_num; ++i) { struct drm_qxl_reloc reloc; struct drm_qxl_reloc __user *u = u64_to_user_ptr(cmd->relocs); @@ -230,7 +229,6 @@ static int qxl_process_single_command(struct qxl_device *qdev, reloc_info[i].dst_bo = cmd_bo; reloc_info[i].dst_offset = reloc.dst_offset + release->release_offset; } - num_relocs++; /* reserve and validate the reloc dst bo */ if (reloc.reloc_type == QXL_RELOC_TYPE_BO || reloc.src_handle) { -- 2.44.0
