vme: move back to staging

2022-06-10T13:38:14+00:00

The VME subsystem graduated from staging into a top-level subsystem in 2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of staging") stating: The VME device drivers have not moved out yet due to some API questions they are still working through, that should happen soon, hopefully. However, this never happened: maintenance of drivers/vme effectively stopped in 2017, with all subsequent changes being treewide cleanups. No hardware driver remains in staging, only the limited user-level access, and I just removed one of the two bridge drivers and the only remaining board. drivers/staging/vme/devices/ was recently moved to drivers/staging/vme_user/, but as the vme_user driver is the only one remaining for this subsystem, it is easier to just move the remaining three source files into this directory rather than keeping the original hierarchy.

bus: Make remove callback return void

2021-07-21T09:53:42+00:00

The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

vme: make remove callback return void

2021-02-09T11:15:07+00:00

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

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

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. Signed-off-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman
