From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
The usage of in_interrupt() in drivers in is phased out.
rtlwifi uses in_interrupt() in the RT_TRACE() debug macro which is
sprinkled all over the driver. RT_TRACE() is almost identical to RTPRINT()
which another hideous debug printk wrapper. The only difference is the
printout of in_interrupt().
The decoding of in_interrupt() as hexvalue is non-trivial and aside of
being phased out for driver use the return value is just by chance the
masked preempt count value and not a boolean.
These home brewn printk debug aids are tedious to work with and provide
only minimal context. They should be replaced by trace_printk() or a debug
tracepoint which automatically records all context information.
To make progress on the in_interrupt() cleanup, make RT_TRACE() use the
RTPRINT() debug function and remove _rtl_dbg_trace().
