This is not a fix patch. So don't add "Fixes" tag 2. Commit subject needs correction... maybe- "cqhci-core: Make use cqhci_halted() routine" 3. This fix tag should be added to your previous patch which fixes a bug. I later noticed that the tag mentioned in previous patch is incorrect. 4. The commit subject says [PATCH 2/2], but the mails were not linked properly, I guess. > Signed-off-by: Seunghwan Baek <sh8267.baek@samsung.com> > --- > drivers/mmc/host/cqhci-core.c | 14 +++++++------- > 1 file changed, 7 insertions(+), 7 deletions(-) > > diff --git a/drivers/mmc/host/cqhci-core.c b/drivers/mmc/host/cqhci-core.c > index a02da26a1efd..178277d90c31 100644 > --- a/drivers/mmc/host/cqhci-core.c > +++ b/drivers/mmc/host/cqhci-core.c > @@ -33,6 +33,11 @@ struct cqhci_slot { > #define CQHCI_HOST_OTHER BIT(4) > }; > > +static bool cqhci_halted(struct cqhci_host *cq_host) > +{ > + return cqhci_readl(cq_host, CQHCI_CTL) & CQHCI_HALT; > +} > + > static inline u8 *get_desc(struct cqhci_host *cq_host, u8 tag) > { > return cq_host->desc_base + (tag * cq_host->slot_sz); > @@ -282,7 +287,7 @@ static void __cqhci_enable(struct cqhci_host *cq_host) > > cqhci_writel(cq_host, cqcfg, CQHCI_CFG); > > - if (cqhci_readl(cq_host, CQHCI_CTL) & CQHCI_HALT) > + if (cqhci_halted(cq_host)) > cqhci_writel(cq_host, 0, CQHCI_CTL); > > mmc->cqe_on = true; > @@ -617,7 +622,7 @@ 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_halted(cq_host)) { > pr_err("%s: cqhci: CQE failed to exit halt state\n", > mmc_hostname(mmc)); > } > @@ -953,11 +958,6 @@ static bool cqhci_clear_all_tasks(struct mmc_host *mmc, unsigned int timeout) > return ret; > } > > -static bool cqhci_halted(struct cqhci_host *cq_host) > -{ > - return cqhci_readl(cq_host, CQHCI_CTL) & CQHCI_HALT; > -} > - > static bool cqhci_halt(struct mmc_host *mmc, unsigned int timeout) > { > struct cqhci_host *cq_host = mmc->cqe_private; > -- > 2.17.1 -ritesh

Code to check whether cqe is in halt state is modified to cqhci_halted, which has already been implemented.
