From: Chaotian Jing <chaotian.jing@xxxxxxxxxxxx> [ Upstream commit f38a9774ddde9d79b3487dd888edd8b8623552af ] when msdc_cmd_is_ready return fail, the req_timeout work has not been inited and cancel_delayed_work() will return false, then, the request return directly and never call mmc_request_done(). so need call mod_delayed_work() before msdc_cmd_is_ready() Signed-off-by: Chaotian Jing <chaotian.jing@xxxxxxxxxxxx> Signed-off-by: Ulf Hansson <ulf.hansson@xxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/mmc/host/mtk-sd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/mmc/host/mtk-sd.c b/drivers/mmc/host/mtk-sd.c index 621c914dc5c01..673f6a9616cd9 100644 --- a/drivers/mmc/host/mtk-sd.c +++ b/drivers/mmc/host/mtk-sd.c @@ -1056,6 +1056,7 @@ static void msdc_start_command(struct msdc_host *host, WARN_ON(host->cmd); host->cmd = cmd; + mod_delayed_work(system_wq, &host->req_timeout, DAT_TIMEOUT); if (!msdc_cmd_is_ready(host, mrq, cmd)) return; @@ -1067,7 +1068,6 @@ static void msdc_start_command(struct msdc_host *host, cmd->error = 0; rawcmd = msdc_cmd_prepare_raw_cmd(host, mrq, cmd); - mod_delayed_work(system_wq, &host->req_timeout, DAT_TIMEOUT); sdr_set_bits(host->base + MSDC_INTEN, cmd_ints_mask); writel(cmd->arg, host->base + SDC_ARG); -- 2.20.1
