Use setup_timer function instead of initializing timer with the function and data fields. Signed-off-by: Allen Pais <allen.lkml@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Use setup_timer function instead of initializing timer with the function and data fields. Signed-off-by: Allen Pais <allen.lkml@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

This reverts commit b899a85.

The firmware for brcmfmac devices includes information regarding regulatory constraints. For certain devices this information is kept separately in a binary form that needs to be downloaded to the device. This patch adds support to download this so-called CLM blob file. It uses the same naming scheme as the other firmware files with extension of .clm_blob. The CLM blob file is optional. If the file does not exist, the download process will be bypassed. It will not affect the driver loading.

Firmware returns proprietary error code when getting error in fil_cmd_data_set or fil_cmd_data_get. Sometimes the vendor tool or utilities which uses libnl may stuck in some commands when wl is down. For example, issue "scan" command after issuing "down" command, the "scan" command will be the blocking call and stuck as no response from firmware. It is caused by that firmware returns BCME_NOTUP(-4) when wl is down, but in Linux the -4 is -EINTR, so libnl catches the error and not pass to upper layer. Because of that, the driver should return Linux error code instead of the proprietary error code, and the tools or utilities need to get the real firmware error code by another command "bcmerrorstr" after receiving the error.

The driver sends an action frame down and waits for a completion signal triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event to continue the process.

When USB or SDIO device got abnormal bus disconnection, host driver tried to clean up the SKBs in PSQ and TXQ. The SKBs pointer in hanger linked to PSQ and TSQ, so we should set the state of skb hanger slot to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb. In brcmf_fws_bus_txq_cleanup it already set BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing SKB, therefore we add this in brcmf_fws_psq_flush to avoid following warning message.

It is observed that sometimes when sdiod is low in tx credits in low rssi scenarios, the data path consumes all sdiod rx all credits and there is no sdiod rx credit available for control path causing host and card to go out of sync resulting in link loss between host and card.

USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

When the connections are defined in firmware, struct device_connection will have the fwnode member pointing to the device node (struct fwnode_handle) of the requested device, and the endpoint will not be used at all in that case.
