 	  If you want MMC/SD/SDIO support, you should say Y here and
 	  also to your specific host controller driver.
 
-config MMC_MQ_DEFAULT
-	bool "MMC: use blk-mq I/O path by default"
-	depends on MMC && BLOCK
-	default y
-	---help---
-	  This option enables the new blk-mq based I/O path for MMC block
-	  devices by default.  With the option the mmc_core.use_blk_mq
-	  module/boot option defaults to Y, without it to N, but it can
-	  still be overridden either way.
