Among all the issues, this finally fixes some of the infoframe regressions seen on g4x and snb systems. - Fixup sdvo infoframe support, this fixes a regression from 2.6.37. - Correctly enable semaphores on snb, we've enabled it already for 3.5, but the dmar check was slightly wrong. - gen6 irq fixlets from Chris. - disable gmbus on i830, the hw seems to be simply broken. - fix up the pch pll fallout (Chris & me). - for_each_ring macro from Chris - I've figured I'll merge this now to avoid backport pain. - complain when the rps state isn't what we expect (Chris). Note that this is shockingly easy to hit and hence pretty much will cause a regression report.

2012-05-20hwmon: (ntc_thermistor) Optimize and fix build warningGuenter Roeck
The following build warning is seen in some configurations: drivers/hwmon/ntc_thermistor.c: In function 'ntc_show_temp': drivers/hwmon/ntc_thermistor.c:293: warning: 'temp' may be used uninitialized in this function Fix the problem by re-arranging the code to overload return values with error codes, and by avoiding error returns whenever possible. Specifically, Simplify lookup_comp() to not return an error. Instead, return i_low == i_high if there is an exact match, or if the ohm value is outside the lookup table range. Modify get_temp_mC() to not return an error. Since it only returns an error after lookup_comp() returned an error, this is quite straightforward after above change. Separate ntc_thermistor_read() into a function to read the resistor value (which can return an error), and the call to get_temp_mC() which doesn't. Call the functions directly from ntc_show_temp(). Code was tested using a test program, comparing the result of the old and new versions of get_temp_mC() for resistor values between 0 and 2,000,000 ohm. As a side effect, this patch reduces code size by approximately 400 bytes on x86_64.
