Subject: [patch 25/35] net: brcmfmac: Use netif_rx_any_context().
Date: Sun, 27 Sep 2020 21:49:11 +0200 [thread overview]
Message-ID: <20200927194922.339094192@linutronix.de> (raw)
In-Reply-To: 20200927194846.045411263@linutronix.de
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
The usage of in_interrupt() in non-core code is phased out. Ideally the
information of the calling context should be passed by the callers or the
functions be split as appropriate.
brcmfmac uses in_interupt() to select the netif_rx*() variant which matches
the calling context. The attempt to consolidate the code by passing an
arguemnt or by distangling it failed due lack of knowledge about this
driver and because the call chains are convoluted and hard to follow.
As a stop gap use netif_rx_any_context() which invokes the correct code
path depending on context which confines the usage of in_interrupt() to
core code.
