Subject: platform-drivers: move probe to .devinit.text in drivers/scsi
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b07193b34c1bc1c184e2d53a62633a73ea9b0a0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

platform-drivers: move probe to .devinit.text in drivers/scsi

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
