mmc: core: sd: Apply BROKEN_SD_DISCARD quirk earlier stable inclusion from stable-6.6.97 commit 3c0c18ef4c7907d1b36119a5c273b7ee01619652 category: bugfix issue: #ICCW0G CVE: NA Signed-off-by: Li Nan <linan122@huawei.com> --------------------------------------- commit 009c3a4bc41e855fd76f92727f9fbae4e5917d7f upstream. Move the BROKEN_SD_DISCARD quirk for certain SanDisk SD cards from the mmc_blk_fixups[] to mmc_sd_fixups[]. This ensures the quirk is applied earlier in the device initialization process, aligning with the reasoning in [1]. Applying the quirk sooner prevents the kernel from incorrectly enabling discard support on affected cards during initial setup.

mmc: sdhci-of-dwcmshc: Prevent illegal clock reduction in HS200/HS400 mode stable inclusion from stable-6.6.119 commit 3009738a855cf938bbfc9078bec725031ae623a4 category: bugfix issue: CVE: CVE-2025-71200 Signed-off-by: Hun_Dun <18967138853@163.com> Co-Authored-By: Agent ------------------------------- mmc: sdhci-of-dwcmshc: Prevent illegal clock reduction in HS200/HS400 mode When operating in HS200 or HS400 timing modes, reducing the clock frequency below 52MHz will lead to link broken as the Rockchip DWC MSHC controller requires maintaining a minimum clock of 52MHz in these modes.
