If anyone has any objections, please let me know. ------------------ From: Keita Aihara [ Upstream commit cd068d51594d9635bf6688fc78717572b78bce6a ] GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that they support poweroff notification and cache, but they are not working correctly. Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff Notification Ready bit also never gets set to 1 within 1 second from the end of busy of CMD49 in sd_poweroff_notify(). This leads to I/O error and runtime PM error state. I observed that the same card manufactured on 01/2024 works as expected. This problem seems similar to the Kingston cards fixed with commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019") and should be handled using quirks. CID for the problematic card is here. 12345641535443002000000145016200 Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now, but would like comments on what naming is appropriate because MID list is not public and not sure it's right.
