Subject: [PATCH] Coresight: tpda/tpdm: remove incorrect __exit annotation
Date: Thu, 26 Jan 2023 17:35:14 +0100	[thread overview]
Message-ID: <20230126163530.3495413-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

'remove' callbacks get called whenever a device is unbound from
the driver, which can get triggered from user space.

Putting it into the __exit section means that the function gets
dropped in for built-in drivers, as pointed out by this build
warning:

`tpda_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-tpda.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-tpda.o
`tpdm_remove' referenced in section `.data' of drivers/hwtracing/coresight/coresight-tpdm.o: defined in discarded section `.exit.text' of drivers/hwtracing/coresight/coresight-tpdm.o

Fixes: 5b7916625c01 ("Coresight: Add TPDA link driver")
Fixes: b3c71626a933 ("Coresight: Add coresight TPDM source driver")
