The patch fixes a couple of issues:
- absence of deallocation of rsi_dev->rx_usb_urb[0] in the driver;
- potential NULL pointer dereference because of lack of checks for memory
allocation success in rsi_init_usb_interface().
By the way, it makes rsi_probe() returning error code instead of 1
and fixes comments regarding returning values.
Found by Linux Driver Verification project (linuxtesting.org).

Right now sleep duration is configured as beacon interval. It should be
the multiple of beacon interval by listen period which helps to
reduce station power consumption.

Earlier the listen interval is used to decide switching between
operating and off-channels during bgscan and to improve throughput,
the listen interval is reduced to 1. After optimiztion in scan
state machine, listen period is not used for decision making and
hence reverting it back to original value.

The p54 driver uses request_firmware() twice, once for actual
firmware and then another time for an optional user overide on
EEPROM, 3826.eeprom. The custom EEPROM is optional but if not
present we'll introduce an extra lag of 60 seconds with udev
present. Annotate we don't want udev nonsense here to avoid
the lag in case its not present.
This was found with the following SmPL patch.
@ firmware_not_critical @
expression cf;
expression config_file;
expression dev;
int ret;
identifier l;
statement S;
@@
- ret = request_firmware(&cf, config_file, dev);
+ ret = request_firmware_direct(&cf, config_file, dev);
if (ret < 0) {
... when != goto l;
when != return ret;
when any
} else {

The users of the fwil put an error message in the log so there is
no need to do the same in the lower level functions in fwil when
the firmware on the device returns an error. Some errors can be
ignored for the driver to function and this will avoid driver users
to point at the low-level error message as potential bug.

semantics
Applying ++ to a bool is equivalent to setting it true, regardless of
its initial value (bools are not uint1_t). Hence the function
wl_get_vif_state_all can only ever return true/false. The only in-tree
caller uses its return value as a boolean. So update its return type,
and since the list traversal and bit testing have no side effects,
just return true immediately. Its return value tells if any vif is in
the specified state, so also rename it to brcmf_get_vif_state_any.

Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.
This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).
As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the
split data.
