The struct brcmf_sdio_dev contains array of sdio functions that are used in the driver. However, during probe func[0] entry was assigned to the function 1 reference. This was corrected upon doing the actual I/O access. This patch makes it more clear by creating the func[0] entry properly and use it as is during I/O access. Reviewed-by:

Functions in dhd_sdio.c that are called with struct brcmf_sdio instance are renamed consistently with brcmf_sdio_ prefix. Reviewed-by:

For the transmission of data a protocol push hdr is performed followed by a bus txdata call. For the new protocol msgbuf this is not workable. Since they are already "loosely" coupled for bcdc protocol they are combined. This means that txdata will go "through" the protocol layer and a seperate protocol push hdr will not be needed anymore.

A new protocol layer msgbuf will be added in the future. This change makes it possible to select the desired layer by the bus driver. USB and SDIO will select BCDC. At the moment nothing is being done with this information. Reviewed-by:

The debug function brcmf_dbg_hex_dump API got changed and the information string should preferably contain a \n at the end of the string. Update the FWIL so debug output looks better. Reviewed-by:

The BCDC functions query_dcmd and set_dcmd both create a msgbuf to be sent to dongle this code is very similar and for optimisation best put in a function. Reviewed-by:

The SDIO send and receive functions in bcmsdh.c are always called with the same parameters. For the driver there is no use-case to call them otherwise so remove those parameters from function prototypes. Reviewed-by:

Commit [3469adb3: fix potential NULL pointer dereference] introduced a check of msg_ind allocation, but omitted allocation of msg_ind->msg. Moreover, it introduced two if statements, which looked a bit clunky. This commit moves allocation code outside of the critical section so there's no need to dance around mutex_unlock, and adds the missing allocation check. Signed-off-by:

RTS protection was turned on once aggregation was enabled but it was never turned off. Remove turning on RTS protection in the LQ command completely as TX_CMD_FLG_PROT_REQUIRE gets set in iwl_mvm_set_tx_cmd for every Tx which is part of an aggregation. This would already cause RTS protection to be used during aggregations. Signed-off-by:

Simplify the code a bit more by extracting the rates table building logic into a separate function and handle setting a fixed rate for debug in a separate flow. Also avoid using and saving ucode rate format in different places. Instead use rs_rate struct and convert to ucode format only when filling the rates table in the LQ command. Signed-off-by:

In case a sync command timeouts or Tx is stuck while a FW error interrupt arrives, we might call iwl_op_mode_nic_error twice before a restart has been initiated. This will cause a reprobe. Unify calls to this function at the transport level and only call it on the first FW error in a given by checking the transport FW error flag. While at it, remove the privately defined iwl_nic_error from PCIE code and use the common callback instead. Signed-off-by:
