mmc: sdhci-msm: Fix the wrapped key handling

2026-04-10T08:29:58+00:00

Inline Crypto Engine (ICE) supports wrapped key generation. While registering crypto profile the supported key types are queried from ICE driver. So the explicit check for RAW key is not needed.

mmc: sdhci-of-dwcmshc: Disable clock before DLL configuration

2026-04-09T15:51:21+00:00

According to the ASIC design recommendations, the clock must be disabled before operating the DLL to prevent glitches that could affect the internal digital logic. In extreme cases, failing to do so may cause the controller to malfunction completely. Adds a step to disable the clock before DLL configuration and re-enables it at the end.

mmc: core: Simplify with scoped for each OF child loop

2026-04-09T15:51:21+00:00

Use scoped for-each loop when iterating over device nodes to simplify the code, but also to ensure the device node reference is automatically released when the loop scope ends. Signed-off-by: Hans Zhang <18255117159@163.com> Reviewed-by: Shawn Lin Signed-off-by: Ulf Hansson

mmc: core: Optimize size of struct mmc_queue_req

2026-04-09T15:49:54+00:00

ioc_count won't be more than MMC_IOC_MAX_CMDS (255), retries won't be more than MMC_NO_RETRIES (6), flags is newly introduced and uses only 1 bit. Therefore let's change them all to become u8. Signed-off-by: Bin Liu Signed-off-by: Ulf Hansson

mmc: vub300: clean up module init

2026-03-31T11:13:47+00:00

Clean up module init by dropping redundant error messages (e.g. allocation and USB driver registration failure will already have been logged) and naming error labels after what they do. Signed-off-by: Johan Hovold Signed-off-by: Ulf Hansson

mmc: vub300: fix use-after-free on disconnect

2026-03-31T11:11:20+00:00

The vub300 driver maintains an explicit reference count for the controller and its driver data and the last reference can in theory be dropped after the driver has been unbound. This specifically means that the controller allocation must not be device managed as that can lead to use-after-free. Note that the lifetime is currently also incorrectly tied the parent USB device rather than interface, which can lead to memory leaks if the driver is unbound without its device being physically disconnected (e.g. on probe deferral). Fix both issues by reverting to non-managed allocation of the controller.

mmc: vub300: fix NULL-deref on disconnect

2026-03-31T11:11:10+00:00

Make sure to deregister the controller before dropping the reference to the driver data on disconnect to avoid NULL-pointer dereferences or use-after-free.

mmc: dw_mmc: Remove dw_mci_start_request wrapper and rename core function

2026-03-31T10:47:12+00:00

The function dw_mci_start_request() was just a thin wrapper around __dw_mci_start_request(). Since it serves almost no functional purpose, remove the wrapper to simplify the code flow. Consequently, rename __dw_mci_start_request() to dw_mci_start_request() so that the core implementation uses the primary name. Signed-off-by: Shawn Lin Signed-off-by: Ulf Hansson
