As described in the added code comment, a reference to .exit.text is ok for drivers registered via module_platform_driver_probe(). Make this explicit to prevent the following section mismatch warning WARNING: modpost: drivers/parport/parport_amiga: section mismatch in reference: amiga_parallel_driver+0x8 (section: .data) -> amiga_parallel_remove (section: .exit.text) that triggers on an allmodconfig W=1 build. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> --- Hello, earlier submission can be found at https://lore.kernel.org/all/49ab91032bf9b57cd5fb6d306c38884d059dce2f.1711748999.git.u.kleine-koenig@pengutronix.de . Changes since then: - (trivially) rebased to v6.9 - Add Greg to To: as the pings to the parport maintainer don't seem to work and Greg was the one who applied parport patches in the past. - Additionally I held git-send-email wrong for the initial submission which made it a bit more complicated to pick up the patch, should be fine now. drivers/parport/parport_amiga.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) base-commit: a38297e3fb012ddfa7ce0321a7e5a8daeb1872b6
