This is one of the most interesting users of module parameters in the
tree, so weaning it off the old-style non-const module_param_call
scheme is a useful exercise.
I was confused by set_param_int/get_param_int (vs. the normal
param_set_int and param_get_int), so I renamed set_param_int to
set_param_timeout, and re-used param_get_int directly instead of
get_param_int. I also implemented param_check_wdog_ifnum and
param_check_timeout, so now the ifnum_to_use and timeout/pretimeout
parameters can just use plain module_param().

sysfs-writable charp arguments need to be locked against modification
(since the old ones may be kfreed underneath us). String arguments
are much simpler, so use them for small strings (eg. IFNAMSIZ).
lkdtm only uses the parameters at module initialization time, so there's
not much point making them writable.

This is more kernel-ish, saves some space, and also allows us to
expand the ops without breaking all the callers who are happy for the
new members to be NULL.
The few places which defined their own param types are changed to the
new scheme (more which crept in recently fixed in following patches).
Since we're touching them anyway, we change get() and set() to take a
const struct kernel_param (which they really are). This causes some
harmless warnings until we fix them (in following patches).
To reduce churn, module_param_call creates the ops struct so the callers
don't have to change (and casts the functions to reduce warnings).
The modern version which takes an ops struct is called module_param_cb.

Two issues are addressed for max8998_set_voltage function.
1. Min/Max Voltage.
max8998_set_voltage had been using the voltage value of
min ( voltage[i] >= max_vol , i )
This is corrected to use:
min ( voltage[i] >= min_vol , i )
2. Ramp Up Delay.
max8998_set_voltage should provide delay for BUCK1/2
if ENRAMP is on. It reads RAMP value from ONOFF4 register to determine
RAMP delay length. However, when max8998_set_voltage's new voltage is
lower than the previous, we don't care because it does not deteriorate
the stability.

[SCSI] reservation conflict after timeout causes device to be taken offline
Flipped us from always returning failed to always returning success in
the name of fixing the problem where reservation conflict returns from
test unit ready cause the device always to be taken offline.
Unfortuantely, it also introduced a problem whereby for commands other
than test unit ready, the eh dispatcher thinks they succeeded when
reservation conflict is returned, whereas in reality they failed. Fix
this by only returning success for the test unit ready case.
