Replace setup("fail_mmc_request") and faulty "ifdef KERNEL" with
a module_param_cb(). The module param mmc_core.fail_request
may be used to set the fault injection attributes during boot time
or module load time.

Akinobu Mita reported that the boot option for mmc fault injection is never
compiled in due to a fauly "ifdef KERNEL" that is never set.
A correct ifdef would be "ifndef MODULE". This patch set adds a

This patch version modifies the power_class_select function prototype.
During device enumeration, when the host tries to read the extended
csd register after switching to higher bus width, the read fails at
higher bus width. So the power_class_select function is modified to
reuse the extended csd
This patch adds the power class selection feature available
for mmc versions 4.0 and above.
During the enumeration stage before switching to the lower
data bus, check if the power class is supported for the
current bus width. If the power class is available then
switch to the power class and use th
