vme: remove unneeded kfree

2018-09-14T13:25:57+00:00

put_device will call vme_dev_release to free vdev, kfree is
unnecessary here.

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

2017-12-18T14:59:18+00:00

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.

VME: Return -EBUSY when DMA list in use

2017-11-08T13:26:50+00:00

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.

vme: Improve 11 size determinations

2017-10-13T20:32:00+00:00

Replace the specification of data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
