Yoshihiro Shimoda 427b00342c mmc: queue: Fix bigger segments usage ... The commit 38c38cb732 ("mmc: queue: use bigger segments if DMA MAP layer can merge the segments") always enables the bugger segments if DMA MAP layer can merge the segments, but some controllers (SDHCI) have strictly limitation about the segments size, and then the commit breaks on the controllers. To fix the issue, this patch adds a new flag MMC_CAP2_MERGE_CAPABLE into the struct mmc_host and the bigger segments usage is disabled as default.
