Hi.
If card is infinitely holding pull down busy line(data 0) while
writing multiple blocks, write will be blocked in
mmc_wait_for_req_done().
I suggest to use wait_for_completion_timeout instread of
wait_for_completion like the below code.
How do you think about my suggestion ?
Thanks.
------------------------------------------------------------------------------------------------------------------
static void mmc_wait_for_req_done(struct mmc_host *host, struct
mmc_request *mrq)
{
unsigned int write_timeout = 0;
if(mrq->data != NULL && (mrq->data->flags & MMC_DATA_WRITE) &&
(mrq->cmd->opcode & MMC_WRITE_MULTIPLE_BLOCK)) {
write_timeout =
usecs_to_jiffies(mrq->data->timeout_ns/1000) * mrq->data->blocks;
wait_for_completion_timeout(&mrq->completion, write_timeout);
}
else wait_for_completion(&mrq->completion);
}
