vme: make remove callback return void

2021-02-09T11:15:07Z

The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct vme_driver::remove return void, too. There is only a single vme driver and it already returns 0 unconditionally in .remove(). Also fix the bus remove function to always return 0. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20210127212329.98517-1-uwe@kleine-koenig.org Signed-off-by: Greg Kroah-Hartman

vme: Fix a possible sleep-in-atomic bug in vme_tsi148

2017-12-18T14:59:18Z

The driver may sleep under a spinlock. The function call path is: tsi148_master_write \ tsi148_master_read (acquire the spinlock) vme_register_error_handler kmalloc(GFP_KERNEL) --> may sleep To fix it, GFP_KERNEL is replaced with GFP_ATOMIC. This bug is found by my static analysis tool(DSAC) and checked by my code review. Signed-off-by: Jia-Ju Bai Signed-off-by: Greg Kroah-Hartman

VME: Return -EBUSY when DMA list in use

2017-11-08T13:26:50Z

The VME subsystem currently returns -EBUSY when trying to free a DMA resource that is busy, but returns -EINVAL when trying to free a DMA list that is in use. Switch to returning -EBUSY when trying to free a DMA list that is in use for consistency and correctness. Signed-off-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman
