2025-07-10T14:08:25Z

commit 14633da0f416fdbb6844d1b295cdc828b666e273 upstream. Adjust some error messages to debug mode to avoid causing misunderstanding it is an error.

mmc: core: sd: Apply BROKEN_SD_DISCARD quirk earlier

2025-07-10T14:08:25Z

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: Add quirk to disable DDR50 tuning

2025-06-27T10:13:11Z

[ Upstream commit 9510b38dc0ba358c93cbf5ee7c28820afb85937b ] Adds the MMC_QUIRK_NO_UHS_DDR50_TUNING quirk and updates mmc_execute_tuning() to return 0 if that quirk is set. This fixes an issue on certain Swissbit SD cards that do not support DDR50 tuning where tuning requests caused I/O errors to be thrown.

mmc: core: Trim trailing whitespace from card product names

2025-03-12T10:30:22Z

Product names for some eMMC chips can include trailing whitespace, which seems to be rather uncommon, but makes emitted messages and /sys properties somewhat unsightly. Here's such an example from a Pine64 PineNote, in which "Biwin ", as the eMMC product name, contains trailing whitespace: mmc0: new HS200 MMC card at address 0001 mmcblk0: mmc0:0001 Biwin 115 GiB mmcblk0: p1 p2 p3 p4 p5 p6 p7 mmcblk0boot0: mmc0:0001 Biwin 4.00 MiB mmcblk0boot1: mmc0:0001 Biwin 4.00 MiB mmcblk0rpmb: mmc0:0001 Biwin 4.00 MiB, chardev (249:0) Trailing whitespace in /sys properties may even cause some unforeseen issues with some scripts, so let's have the trailing whitespace trimmed in product names for eMMC chips. Although not observed yet by the author of these changes, the same trailing whitespace may appear in SD card product names, so let's trim them as well, which can't hurt. Touch-up one comment as well, by using proper capitalization.
