mmc: sdhci-esdhc-imx: make "no-mmc-hs400" works

2023-05-09T09:55:02Z

After commit 1ed5c3b22fc7 ("mmc: sdhci-esdhc-imx: Propagate ESDHC_FLAG_HS400* only on 8bit bus"), the property "no-mmc-hs400" from device tree file do not work any more. This patch reorder the code, which can avoid the warning message "drop HS400 support since no 8-bit bus" and also make the property "no-mmc-hs400" from dts file works.

mmc: sdhci-cadence: Fix an error handling path in sdhci_cdns_probe()

2023-05-09T09:16:15Z

If devm_reset_control_get_optional_exclusive() fails, some resources still need to be released. So branch to the error handling path instead of returning directly.

mmc: block: ensure error propagation for non-blk

2023-05-09T09:16:15Z

Requests to the mmc layer usually come through a block device IO. The exceptions are the ioctl interface, RPMB chardev ioctl and debugfs, which issue their own blk_mq requests through blk_execute_rq and do not query the BLK_STS error but the mmcblk-internal drv_op_result. This patch ensures that drv_op_result defaults to an error and has to be overwritten by the operation to be considered successful. The behavior leads to a bug where the request never propagates the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged) and thus may assume that their call executed successfully when it did not. While always checking the blk_execute_rq return value would be advised, let's eliminate the error by always setting drv_op_result as -EIO to be overwritten on success (or other error) Fixes: 614f0388f580 ("mmc: block: move single ioctl() commands to block requests") Signed-off-by: Christian Loehle Acked-by: Adrian Hunter Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/59c17ada35664b818b7bd83752119b2d@hyperstone.com Signed-off-by: Ulf Hansson
