The value of 'start' entry is no change whenever writing 0 to configfs. So the endpoint that stopped once can't restart.
Fixes: d74679911610 ("PCI: endpoint: Introduce configfs entry for configuring EP functions") Cc: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> --- drivers/pci/endpoint/pci-ep-cfs.c | 1 + 1 file changed, 1 insertion(+)
Since the possibility of restarting endpoint is up to each controller, if restart is prohibited on purpose for some reason, this patch can be ignored.
