[PATCH 4.4 052/131] Revert "mmc: block: dont use parameter prefix if built as module"

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit a5ebb87db84392edfd3142c3a6a78431d820a789 ]

This reverts commit 829b6962f7e3cfc06f7c5c26269fd47ad48cf503.

Revert this change as it causes a sysfs path to change and therefore
introduces and ABI regression. More precisely Android's vold is not being
able to access /sys/module/mmcblk/parameters/perdev_minors any more, since
the path becomes changed to: "/sys/module/mmc_block/..."

Fixes: 829b6962f7e3 ("mmc: block: don't use parameter prefix if built as
module")
