Subject: [PATCH] mux: adgs1408: Add mod_devicetable.h and remove of_match_ptr

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

Enables probing via the ACPI PRP0001 route but more is mostly about
removing examples of this that might get copied into new drivers.

Also fixes
  drivers/mux/adgs1408.c:112:34: warning: unused variable 'adgs1408_of_match
as has been reported recently.

Fixes: e9e40543ad5b ("spi: Add generic SPI multiplexer")

Hi Greg,

Here's a single mux patch. It's been in -next for a couple of days, and
it all looks straight-forward to me. Please pass on to Linus whenever
convenient.

Cheers,
Peter
