cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Scripted using

  git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
  do
    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {
        gsub(/__stringify\(ns\)/, "ns");
        print;
        next;
      }
      /^#define MODULE_IMPORT_NS/ {
        gsub(/__stringify\(ns\)/, "ns");
        print;
        next;
      }
      /MODULE_IMPORT_NS/ {
        $0 = gensub(/MODULE_IMPORT_NS\(([^)]*)\)/, "MODULE_IMPORT_NS(\"\\1\")", "g");

spi: Switch back to struct platform_driver::remove() 
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/spi to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

The change for the spi-npcm-fiu stands out in the diffstat because the
inconsistent formatting style of the platform_driver initializer is
fixed to match the other struct initializer in the file.

spi: pxa2xx: Move PM runtime handling to the glue drivers 
PCI and platform buses have different defaults for runtime PM.
In particular PCI probe is assumed to be called when PM runtime
is enabled by the PCI core. In this case if we try enable it again
the PM runtime complaints with

    pxa2xx_spi_pci 0000:00:07.0: Unbalanced pm_runtime_enable!

Fix this by moving PM runtime handling from the SPI PXA2xx core
to the glue drivers.

spi: pxa2xx: Do not override dev->platform_data on probe 
The platform_data field may be supplied by legacy board code.
In other cases we override it, and module remove and probe cycle
will crash the kernel since it will carry a stale pointer.

Fix this by supplying a third argument to the pxa2xx_spi_probe()
and avoid overriding dev->platform_data.

spi: pxa2xx: Move platform driver to a separate file 
The spi-pxa2xx.c is bloated with a platform driver code while
pretending to provide a core functionality. Make it real core
library by splitting out the platform driver to a separate file.
