Subject: [PATCH v2 2/2] arm: perf: Mark as non-removable
Date: Wed, 21 Dec 2016 16:03:40 +0100	[thread overview]
Message-ID: <20161221150340.25657-3-alexander.stein@systec-electronic.com> (raw)
In-Reply-To: <20161221150340.25657-1-alexander.stein@systec-electronic.com>

This driver can only built into the kernel. So disallow driver bind/unbind
and also prevent a kernel error in case DEBUG_TEST_DRIVER_REMOVE is
enabled.
