The newly added driver causes lots of warnings like

drivers/staging/rtl8723bs/core/rtw_recv.c: In function 'validate_recv_frame':
drivers/staging/rtl8723bs/core/rtw_recv.c:1602:4: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
    DBG_COUNTER(adapter->rx_logs.core_rx_pre_data_handled);
drivers/staging/rtl8723bs/core/rtw_xmit.c: In function 'update_attrib':
drivers/staging/rtl8723bs/core/rtw_xmit.c:726:3: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
   DBG_COUNTER(padapter->tx_logs.core_tx_upd_attrib_unknown);
drivers/staging/rtl8723bs/hal/HalPhyRf.c: In function 'ODM_TXPowerTrackingCallback_ThermalMeter':
drivers/staging/rtl8723bs/hal/HalPhyRf.c:146:4: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
drivers/staging/rtl8723bs/hal/HalPhyRf.c:529:6: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
drivers/staging/rtl8723bs/hal/HalPhyRf.c:559:6: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]

When DBG_COUNTER() etc is defined as a non-empty macro, we get the intended
behavior and no warning. Using no_printk() for printing helper functions
as the added advantage of compile-time checking format strings

Removed the usb_device_reset(), replace with call to usb_reset_device()
directly. Plus it removes the confusing function name and addressed
the checkpatch warning. This change also swaps string in the dev_warn() call
with __func__ argument to "vt6656_probe" instead of literal string
"usb_reset_device".

Driver currently uses abbreviations 'mgt' and 'mngmt' for
'management'. Also 'power' is sometimes abbreviated to 'pow' and other
times not. It makes the code easier to read and easier to modify if
one abbreviation is used throughout the driver. 'mgmt' is widely
accepted as an abbreviation of 'management'. 'power' can be spelled
out in full, the extra two characters aids readability without an
excessive cost.

Make abbreviation of 'management' uniform across the driver, function
names, preprocessor defined constants, and enumeration types.
