Subject: [PATCH] rtc: davinci: remove incorrect reference to probe function
Date: Mon, 12 Oct 2015 15:14:05 +0200 [thread overview]
Message-ID: <5677325.oZsHpDNL2Z@wuerfel> (raw)
The davinci rtc driver uses the module_platform_driver_probe()
helper to call the probe function and mark it as __init, but
it also puts a reference into its davinci_rtc_driver function.
This will crash if we ever get a deferred probe and the probe
function is called again after the init section has been removed.
kbuild warns about this:
WARNING: vmlinux.o(.data+0x1aa2b4): Section mismatch in reference from the variable davinci_rtc_driver to the function .init.text:davinci_rtc_probe()
The variable davinci_rtc_driver references
the function __init davinci_rtc_probe()
This patch removes the .probe callback from the platform driver,
which avoids those problems.
