The documentation says that the result of raw * scale should be in microvolts,
but in reallity all drivers actually report the scale so that the result is in
millivolts. So update the documentation to match reallity.

Don't call hid_open_device till there is actually an user. This saves
power by not opening underlying transport for HID. Also close device
if there are no active mfd client using HID sensor hub.

Turns out that LL_MRF_RETURN is "void" so loop_make_request() would fall
through to the error path for a successful call. Either this never
matters, or the error path really doesn't do anything.
Fix it up to do what the code is written to look like it is doing, if
that really is what it should be doing is another story...

Fix build errors when GPIO_CS5535=m and FB_OLPC_DCON=y
by preventing that kconfig combination.
These build errors are caused by having a kconfig bool symbol
(FB_OLPC_DCON_1) that depend on a tristate symbol (GPIO_CS5535),
but when the tristate symbol is =m, the bool symbol is =y.
