uio: uio_hv_generic: use devm_kzalloc() for private data alloc

2020-12-09T18:59:00+00:00

This is a minor cleanup for the management of the private object of this
driver. The allocation can be tied to the life-time of the hv_device
object.
This cleans up a bit the exit & error paths, since the object doesn't need
to be explicitly free'd anymore.

uio: uio_fsl_elbc_gpcm: use device-managed allocators

2020-12-09T18:59:00+00:00

This change moves all the simple allocations to use device-managed
allocator functions. This way their life-time is tied to the
platform_device object, so when this gets free'd these allocations also get
cleaned up.
The final effect is that error & exit paths get cleaned up a bit.

uio: uio_aec: use devm_kzalloc() for uio_info object

2020-12-09T18:59:00+00:00

The uio_info object is free'd last, so it's life-time is tied PCI device
object. Using devm_kzalloc() cleans up the error path a bit and the exit
path.

uio: uio_netx: use devm_kzalloc() for or uio_info object

2020-12-09T18:58:54+00:00

This change uses the devm_kzalloc() function to tie the life-time of the
uio_info object to PCI device. This cleans up the exit & error path a bit.

uio: uio_sercos3: use device-managed functions for simple allocs

2020-12-09T18:58:54+00:00

This change converts the simple allocations [kzalloc()] to devm_kzalloc()
tying the life-time of these objects to the PCI device object.
It cleans up the error and exit path and bit, and does a minor correction
that -ENOMEM is returned (vs -ENODEV) in case the 'priv' object cannot be
allocated.

uio: uio_dmem_genirq: finalize conversion of probe to devm_ handlers

2020-12-09T18:58:22+00:00

This moves move pm_runtime_disable on a devm_add_action_or_reset() handler.
And with the use of the devm_uio_register_device() function, the remove
hook is no longer required.

uio: uio_dmem_genirq: convert simple allocations to device-managed

2020-12-09T18:58:22+00:00

This change converts the simple allocations in the driver to used
device-managed allocation functions.
This removes the error path entirely in the probe function, and reduces
some code in the remove function.

uio/uio_pci_generic: remove unneeded pci_set_drvdata()

2020-12-09T18:57:20+00:00

The pci_get_drvdata() was moved during commit ef84928cff58
("uio/uio_pci_generic: use device-managed function equivalents").

Storing a private object with pci_set_drvdata() doesn't make sense
since that change, since there is no more pci_get_drvdata() call in the
driver to retrieve the information.

This change removes it.
