Subject: [PATCH 05/10] softirq: Replace BUG() after if statement with BUG_ON
Date: Fri, 27 Mar 2020 21:23:52 +0000	[thread overview]
Message-ID: <20200327212358.5752-6-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200327212358.5752-1-jbi.octave@gmail.com>

Coccinelle reports a warning tasklet_action_common()

WARNING: Use BUG_ON instead of if condition followed by BUG

To fix this, BUG() is replaced by BUG_ON() with the recommended suggestion
