-Subject: [PATCH] Revert "mmc: renesas_sdhi_internal_dmac: limit DMA RX for old
- SoCs"
-
-This reverts commit fbd708880ca045a4583a4d2ca2f67e8a41ddab62.
-
-It solves the problem that SD card / eMMC partition information can not
-be read correctly on a device operating with force_pio.
-
-This revert is a workaround due to difference effect with upstream code.
