The changelog should say something like:
This patch is a cleanup which replaces rtw_malloc(wep_total_len)
with kzalloc() and removes the memset().
The rtw_malloc() does GFP_ATOMIC allocations when in_atomic() is true.
But as the comments for in_atomic() describe, the in_atomic() check
should not be used in driver code. The in_atomic() check is not
accurate when preempt is disabled.
In this code we are not in IRQ context and we are not holding any
spin_locks so GFP_KERNEL is safe.
