Small suggestion below. But this still looks good to me, so either ways- Reviewed-by: Ritesh Harjani <ritesh.list@gmail.com> > > diff --git a/drivers/mmc/host/cqhci-core.c b/drivers/mmc/host/cqhci-core.c > index c14d7251d0bb..a02da26a1efd 100644 > --- a/drivers/mmc/host/cqhci-core.c > +++ b/drivers/mmc/host/cqhci-core.c > @@ -617,7 +617,7 @@ static int cqhci_request(struct mmc_host *mmc, struct mmc_request *mrq) > cqhci_writel(cq_host, 0, CQHCI_CTL); > mmc->cqe_on = true; > pr_debug("%s: cqhci: CQE on\n", mmc_hostname(mmc)); > - if (cqhci_readl(cq_host, CQHCI_CTL) && CQHCI_HALT) { > + if (cqhci_readl(cq_host, CQHCI_CTL) & CQHCI_HALT) { There is already a helper cqhci_halted().
