The variable dev is checked in:
if (dev)
This indicates that it can be NULL. If so, a null-pointer dereference will
occur:
priv = rtllib_priv(dev);
However, the value of priv is not used in the remaining part of this
function. Thus the else-branch can be removed to fix this posible
null-pointer dereference.

After commit 71f09c5ae9 ("staging: r8188eu: Remove wrapper around
vfree"), the driver fails to build on Hexagon due to an implicit
declaration in several different files:
drivers/staging/r8188eu/core/rtw_mlme.c:129:3: error: implicit
declaration of function 'vfree'
[-Werror,-Wimplicit-function-declaration]
vfree(pmlmepriv->free_bss_buf);
^
1 error generated.
Previously, vfree() was only called in osdep_service.c, which includes
vmalloc.h for vmalloc() and vfree(). Now, the driver relies on vfree()
getting implicitly included from another file.
Hoist the vmalloc.h include from osdep_service.c to osdep_service.h so
that the driver continues to build fine on all architectures.

Note that this patch does not address any warnings that checkpatch

that are too long. These problems will be addressed in a separate

Remove rtw_ioctl function from os_dep/ioctl_linux.c, its declaration
in include/osdep_intf.h, and finally its inclusion as the value of the
.ndo_do_ioctl member of struct net_device_ops rtw_netdev_ops in
os_dep/os_intfs.c.
The e-mail from Arnd Bergmann at:
https://lore.kernel.org/linux-next/CAK8P3a0WRMNmBmBDerZ0nWPdFZKALnxrj-uUFBkTP-MOtv48vg@mail.gmail.com
explains the justification for this approach. Essentially, changes from
net-next make the existing function and its use of SIOCDEVPRIVATE ioctls
unworkable without changes.
Functions called from rtw_ioctl that are now no longer accessible will
be cleaned up in further patches. Additionally, once these changes have
made their way downstream to the staging branch, we can modify and
reconnect rtw_android_priv_cmd via ndo_siocdevprivate in struct
net_device_ops.

With the RT_TRACE print removed, the rtw_wx_set_freq function is now
