| Series | [1/4] Bluetooth: btmtksdio: drop the unnecessary variable created | expand |
Hi Sean, > btmtksdio have to rely on MMC_PM_KEEP_POWER in pm_flags to avoid that > SDIO power is being shut off during the device is in suspend. That fixes > the SDIO command fails to access the bus after the device is resumed. > > Fixes: 7f3c563c575e7 ("Bluetooth: btmtksdio: Add runtime PM support to SDIO based Bluetooth") > Co-developed-by: Mark-yw Chen <mark-yw.chen@mediatek.com> > Signed-off-by: Mark-yw Chen <mark-yw.chen@mediatek.com> > Signed-off-by: Sean Wang <sean.wang@mediatek.com> > --- > drivers/bluetooth/btmtksdio.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/drivers/bluetooth/btmtksdio.c b/drivers/bluetooth/btmtksdio.c > index 4c46c62e4623..cae1fcd15512 100644 > --- a/drivers/bluetooth/btmtksdio.c > +++ b/drivers/bluetooth/btmtksdio.c > @@ -1040,6 +1040,8 @@ static int btmtksdio_runtime_suspend(struct device *dev) > if (!test_bit(HCI_RUNNING, &bdev->hdev->flags)) > return 0; > > + sdio_set_host_pm_flags(func, MMC_PM_KEEP_POWER); > + > sdio_claim_host(bdev->func); > > sdio_writel(bdev->func, C_FW_OWN_REQ_SET, MTK_REG_CHLPCR, &err); if this makes sense without 2/4 patch, then please re-send.
