This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.
In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

Remove dev_err() calls for conditions caused by invalid userspace
input. Logging them clutters the kernel log, especially if userspace

Also, consolidate the write validation checks into a single condition.
Remove the check for zero-length packets as this condition cannot
occur during normal operation. According to the Xilinx AXI4-Stream
FIFO Product Guide (PG080), in the Receive Length Register (RLR)
description: "The smallest packet that can be received is 1 byte."
A zero-length packet would indicate a bug in the IP core itself.
Module parameters for timeouts are a poor interface choice as they
affect all device instances globally rather than being configurable
per file descriptor.
The current implementation also returns -EAGAIN on timeout, requiring
userspace to implement retry loops around blocking operations.
Remove the read_timeout and write_timeout module parameters. The next
commit adds poll() support, allowing applications to implement timeout
handling using standard poll()/select() interfaces.

The packet transmission path in rtw_xmit.c contained TODO comments
indicating a missing lock. This patch implements spin_lock_bh and
spin_unlock_bh around the station attribute update section.
This prevents a potential race condition where station security and
PHY information could be modified on another CPU core during
transmission. The use of _bh variants ensures safety in bottom-half
contexts common in network transmit paths.
Verified that psta is NULL-checked prior to acquisition and that no
double-unlocks occur on the exit path.
The MAC_ARG(x) macro is a useless identity macro that just returns its
argument unchanged. It was used alongside the %pM format specifier for
printing MAC addresses, but %pM already handles MAC address formatting
directly without needing any wrapper macro.
This commit removes the macro definition from both:
The TODO lines about "checkpatch cleanup" and "kernel coding style"

Note: checkpatch reports a false positive WARNING for sm750.c line 36

Switch from the deprecated of_property_read_bool() to the common

Since the driver is no longer strictly dependent on Device Tree,
include <linux/mod_devicetable.h> directly for the struct
of_device_id definition, instead of relying on implicit inclusion
via <linux/of_irq.h>, which has been removed as it is unused.
Also rename apb_ctrl_get_devtree_data() to apb_ctrl_get_fw_data()

Fix several instances where operators lacked spaces around them.
