[PATCH 00/12] SPI GPIO improvements

[Andrey Smirnov]

Everyone:

This series contains a fix ("spi: Don't call spi_get_gpio_descs()
before device name is set) and improvements for SPI GPIO and driver I
made while looking at that code recently. Hopefully each patch is
self-explanatory.

Feedback is welcome!

Thanks,
Andrey Smirnov

  spi: gpio: Drop unused spi_to_pdata()
  spi: gpio: Add local struct device pointer in spi_gpio_probe()
  spi: gpio: Add local struct spi_bitbang pointer in spi_gpio_probe()
  spi: gpio: Simplify SPI_MASTER_NO_TX check in spi_gpio_probe()
  spi: gpio: Drop unused pdata copy in struct spi_gpio
  spi: gpio: Don't request CS GPIO in DT use-case
  spi: Don't call spi_get_gpio_descs() before device name is set
  spi: gpio: Drop mflags argument from spi_gpio_request()
  spi: gpio: Drop unused pdev field in struct spi_gpio
  spi: gpio: Make sure spi_master_put() is called in every error path
  spi: bitbang: Introduce spi_bitbang_init()
  spi: gpio: Use devm_spi_register_master()
