[PATCH AUTOSEL 5.9 07/55] usb: gadget: goku_udc: fix potential crashes in probe

[Sasha Levin]

From: Evgeny Novikov <novikov@ispras.ru>

[ Upstream commit 0d66e04875c5aae876cf3d4f4be7978fa2b00523 ]

goku_probe() goes to error label "err" and invokes goku_remove()
in case of failures of pci_enable_device(), pci_resource_start()
and ioremap(). goku_remove() gets a device from
pci_get_drvdata(pdev) and works with it without any checks, in
particular it dereferences a corresponding pointer. But
goku_probe() did not set this device yet. So, one can expect
various crashes. The patch moves setting the device just after
allocation of memory for it.

space content to user space, the 'event' the memory space
pointed to by the 'event' pointer need be freed.
