6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonathan Bell <jonathan@xxxxxxxxxxxxxxx>
commit 469e5e4713989fdd5e3e502b922e7be0da2464b9 upstream.
Applying MMC_QUIRK_BROKEN_SD_CACHE is broken, as the card's SD quirks are
referenced in sd_parse_ext_reg_perf() prior to the quirks being initialized
in mmc_blk_probe().
To fix this problem, let's split out an SD-specific list of quirks and
apply in mmc_sd_init_card() instead. In this way, sd_read_ext_regs() to has
the available information for not assigning the SD_EXT_PERF_CACHE as one of
the (un)supported features, which in turn allows mmc_sd_init_card() to
properly skip execution of sd_enable_cache().
Fixes: c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019")
