Currently the code handles this in the abstraction above. We want to remove
that abstraction so begin by pushing down the sanity check. Unfortunately
at this point we can't simply fix the init order.

Introduce the DPAA2 Ethernet driver, which manages Datapath
Network Interface (DPNI) objects discovered on the MC bus.
In addition to DPNIs, the Ethernet driver uses several other
MC objects to build a network interface abstraction: buffer
pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs).
A more detailed description of the driver can be found in the
associated README file.

I ran into this warning during randconfig testing:

drivers/staging/rtl8723bs/os_dep/rtw_proc.c:738:25: error: unused variable 'drv_proc' [-Werror=unused-variable]

drivers/staging/rtl8723bs/os_dep/rtw_proc.c:762:25: error: unused variable 'drv_proc' [-Werror=unused-variable]
The problem is that the code procfs code gets built even when CONFIG_PROC_FS
is disabled, but some functions are turned into empty stubs then. This
is easily addressed by adding an #ifdef around the definition of the
CONFIG_PROC_DEBUG macro.
However, I could not bear looking at the macro name that clashes with the
Kconfig name space, so I also renamed it to simply PROC_DEBUG, along with
the other rtl8723bs specific CONFIG_DEBUG_* macros that I renamed the same
way. This is consistent with how we handle the same checks in the non-staging
rtlwifi driver.
As the code path for !CONFIG_PROC_DEBUG had not been tested properly, it
turned out to be incorrect and requires adding 'static inline' annotations
for the stub handlers, and moving some variables around.
