+Subject: mmc: moxart: fix 4-bit bus width and remove 8-bit bus width
+
+From: Sergei Antonov <saproj@gmail.com>
+
+commit 35ca91d1338ae158f6dcc0de5d1e86197924ffda upstream.
+
+According to the datasheet [1] at page 377, 4-bit bus width is turned on by
+bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define
+BUS_WIDTH_4 BIT(1)
+
+BIT(1) does not work but BIT(2) works. This has been verified on real MOXA
+hardware with FTSDC010 controller revision 1_6_0.
+
+The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8
+BIT(2). Additionally, 8-bit bus width mode isn't supported according to the
+datasheet, so let's remove the corresponding code.

+Fix this by adding sanity check on extended system files' directory inode
+to ensure that it is directory, just like ntfs_extend_init() when mounting
+ntfs3.
