container_of() works by subtracting the offset of the member. The math can't really return a zero here.

2012-05-15NFC: Cache the core NFC active target pointer instead of its indexEric Lapuyade
The NFC Core now caches the active nfc target pointer, thereby avoiding the need to lookup the target table for each invocation of a driver ops. Consequently, pn533, HCI and NCI now directly receive an nfc_target pointer instead of a target index.

2012-05-15ath9k_hw: Fix RTT calibrationSujith Manoharan
This patch fixes multiple issues with the current RTT implementation in ath9k. * The data that is obtained from the RTT interface registers are stored in 31:5 - mask out the extra bits when reading them. * A history buffer is maintained which is not needed at all. Remove this array and just store the baseband data for each chain (or bank). * A 'num_readings' variable was being used to handle the last entry. But it was being used in an improper manner, with the result that the RTT values were never being written to the RTT Interface registers. Fix this by using a simple flag. * Stop baseband operations before programming the calibration values to the HW. * Do not restore RX gain settings as part of RTT.
