[PATCH v1 0/5] media: ir-spi: A few cleanups

[Andy Shevchenko]

While removing of_gpio.h where it's being unused, this driver seems to 
deserve more love. Hence this series.

  media: ir-spi: Don't use "proxy" headers
  media: ir-spi: Make use of device properties
  media: ir-spi: Utilise temporary variable for struct device
  media: ir-spi: Remove trailing comma in the terminator entry

this goes over 80 characters, though. Not an error, but not worth
a change either.

I'm not going block the patch as the rest is OK.

Thank you!

Btw, don't you want to either add your entry into .mailcap and/or update your
email address in this source file (and maybe others)? I Cc'ed you only after
I looked closer to the sources...

yes, will do... I also noticed that lots of updates are missing...

I've been far from all this for too long, so that I have still
