2011-08-11hwmon: (ibmaem) add missing kfreeJulia Lawall
rs_resp is dynamically allocated in aem_read_sensor(), so it should be freed before exiting in every case. This collects the kfree and the return at the end of the function.

2011-08-11hwmon: (pmbus/lm25066) Ignore byte writes to non-zero pagesGuenter Roeck
pmbus_clear_faults() attempts to clear faults on non-existing real pages. As a result, the command error bit in the status register is set, and faults are not really cleared. All byte writes to non-zero pages are requests to clear the status register on that page. Since non-zero pages are virtual and do not exist on the chip, there is nothing to do, and such requests have to be ignored. This fixes above problem.

2011-07-28hwmon: (lm90) Simplify handling of extended local temp registerJean Delvare
The optional extended local temperature register can never have address 0, as this address is already used by another register. Thus we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on reg_local_ext being non-zero to determine if a given chip has this extension or not. This makes the code more simple.

2011-07-28hwmon: (pmbus) Add support for peak attributesGuenter Roeck
Most PMBus devices provide manufacturer specific commands to read low and/or high peak values for some or all of its sensors. To support providing those values as lowest/highest attributes to the user, introduce virtual PMBus commands. Those commands reside outside the normal command set and have to be implemented in device specific code, which map the virtual commands to device specific commands.

2011-07-28hwmon: (pmbus) Add support for virtual pagesGuenter Roeck
Some PMBus chips have non-standard sensor registers. An easy way to support such sensors is to introduce virtual pages and map the non-standard registers into standard registers on an extra page. For this to work, the code verifying if the configured number of pages exists has to be removed. Since a wrong number of pages can only be configured in a front-end driver, this should not have a practical impact since the resulting errors should be found during development and testing. Also, functions to read the chip status while checking if a command register exists must be modified to no longer set the page register before reading the status, since the physical page associated with the checked register may not exist. This does not make a functional difference since the page was already set when the attempt to read the register was made.
