Subject: [patch 19/35] net: zd1211rw: Remove ZD_ASSERT(in_interrupt())
Date: Sun, 27 Sep 2020 21:49:05 +0200	[thread overview]
Message-ID: <20200927194921.746408581@linutronix.de> (raw)
In-Reply-To: 20200927194846.045411263@linutronix.de

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

in_interrupt() is ill defined and does not provide what the name
suggests. The usage especially in driver code is deprecated and
a tree wide effort to clean up and consolidate the (ab)usage of
in_interrupt() and related checks is happening.

handle_regs_int() is always invoked as part of URB callback which is either
invoked from hard or soft interrupt context.

Remove the magic assertion.
