scsi: esp_scsi: move dma mapping into the core code

2018-10-16T03:00:38+00:00

Except for the mac_esp driver, which uses PIO or pseudo DMA, all drivers
share the same dma mapping calls.  Move the dma mapping into the core
code using the scsi_dma_map / scsi_dma_unmap helpers, with a special
identify mapping variant triggered off a new ESP_FLAG_NO_DMA_MAP flag
for mac_esp.

scsi: esp_scsi: remove the dev argument to scsi_esp_register

2018-10-16T03:00:38+00:00

We can simplify use esp->dev now.

scsi: esp_scsi: use strong typing for the dev field

2018-10-16T03:00:38+00:00

esp->dev is a void pointer that points either to a struct device, or a
struct platform_device.  As we can easily get from the device to the
platform_device if needed change it to always point to a struct device
and properly type the pointer to avoid errors.

scsi: sun_esp: don't use GFP_ATOMIC for command block allocation

2018-10-16T03:00:38+00:00

esp_sbus_map_command_block is called straight from the probe routine
without any locks held, so we can safely use GFP_KERNEL here.

scsi: sun_esp: fix device reference leaks

2017-06-28T01:46:55+00:00

Make sure to drop the reference to the dma device taken by
of_find_device_by_node() on probe errors and on driver unbind.

scsi: drop owner assignment from platform_drivers

2014-10-20T14:21:33+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

Drivers: scsi: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

dt/sparc: Eliminate users of of_platform_{,un}register_driver

2011-02-28T08:36:39+00:00

Get rid of old users of of_platform_driver in arch/sparc.  Most
of_platform_driver users can be converted to use the platform_bus
directly.

of/device: Replace struct of_device with struct platform_device

2010-08-06T15:25:50+00:00

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

of/platform: remove all of_bus_type and of_platform_bus_type references

2010-07-24T15:57:52+00:00

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus.  This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.
