Wolfram Sang 14ac00e033 spi: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Axel Lin aa0fe82629 spi: Use reinit_completion at appropriate places
Calling init_completion() once is enough.
For the rest of the iterations, call reinit_completion() instead.

Paul Gortmaker 3a44623d5e spi: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Wei Yongjun 9637b86fd1 spi: bcm63xx: fix reference leak to master in bcm63xx_spi_remove()
Once a spi_master_get() call succeeds, we need an additional
spi_master_put() call to free the memory, otherwise we will
leak a reference to master. Fix by removing the unnecessary
spi_master_get() call.

Jonas Gorski 20e9e78f8b spi/bcm63xx: don't reject reads >= 256 bytes
The rx_tail register is only 8 bit wide, so it will wrap around
after 256 read bytes. This makes it rather meaningless, so drop any
usage of it to not treat reads over 256 as failed.

Julia Lawall de0fa83c41 spi/spi-{bcm63xx.c,bfin-v3.c}: simplify use of devm_ioremap_resource
Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
// </smpl>
