Subject: [PATCH 1/7] padata: remove exit routine
Date: Thu, 30 Apr 2020 16:11:19 -0400	[thread overview]
Message-ID: <20200430201125.532129-2-daniel.m.jordan@oracle.com> (raw)
In-Reply-To: <20200430201125.532129-1-daniel.m.jordan@oracle.com>

padata_driver_exit() is unnecessary because padata isn't built as a
module and doesn't exit.

padata's init routine will soon allocate memory, so getting rid of the
exit function now avoids pointless code to free it.
