[PATCH 5.10 005/202] platform/x86: hp-wmi:: Mark driver struct with __refdata to prevent section mismatch warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit 5b44abbc39ca15df80d0da4756078c98c831090f ]

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 a section mismatch warning:

	WARNING: modpost: drivers/platform/x86/hp/hp-wmi: section mismatch in reference: hp_wmi_driver+0x8 (section: .data) -> hp_wmi_bios_remove (section: .exit.text)

Fixes: c165b80cfecc ("hp-wmi: fix handling of platform device")
