This is an NFC driver for NXP pn544. Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers. Signed-off-by:

nfc_llcp_general_bytes is defined in nfc/core.c as: nfc_llcp_general_bytes(struct nfc_dev *dev, size_t *gb_len). as in nfc/nfc.h: nfc_llcp_general_bytes(struct nfc_dev *dev, u8 *gb_len), if CONFIG_NFC_LLCP is not defined. so we got some warnings, net/nfc/core.c:207:2: warning: passing argument 2 of ‘nfc_llcp_general_bytes’ from incompatible pointer type [enabled by default] net/nfc/nfc.h:87:19: note: expected ‘u8 *’ but argument is of type ‘size_t *’ Signed-off-by:

container_of() works by subtracting the offset of the member. The math can't really return a zero here. Sometimes people check it when they actually meant to check something else but in this case we can just remove the check. Signed-off-by:

It is now specified that nfc_target_found() and nfc_target_lost() core functions must not be called from an atomic context. This allow us to serialize calls and protect the targets table using the nfc device lock instead of a spinlock. Signed-off-by:

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. Cc: Ilan Elias <ilane@ti.com> Signed-off-by:

There is a dummy read of a PCI MMIO register that occurs before the SSB bus has been powered, which is an error. This bug has not been seen earlier, but was apparently exposed when udev was updated to version 182. Signed-off-by:

Both brcmf_sdcard_cfg_read/write and brcmf_sdcard_reg_read/write are used as interface functions for register access of SDIO WiFi dongle. A unified interface brcmf_sdio_regr/w is introduced in this patch in order to simplify the interface and keep the complexity within the lower layer. Reviewed-by:

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. Signed-off-by:

If the BA session is torn down before we had a chance to start it we shouldn't disable the AGG tx queues that weren't enabled. This can happen in two cases: 1) We get a delBA before we drained our Tx queues in agg start flow 2) We didn't get the (successfull) addBA response on time Reported-by:
