837d4f8f41 spi-gpio-custom: fix section mismatch
This fixes this section mismatch warning:
The function spi_gpio_custom_get_slave_cs() references
the variable __initdata bus_nump.
This is often because spi_gpio_custom_get_slave_cs lacks a __initdata
annotation or the annotation of bus_nump is wrong.

6bb50e4df1 package/kernel: add spi-gpio-custom module
The package makes it possible to create custom SPI
buses via GPIO lines.

This module is based on i2c-gpio-custom and allows to
configure an SPI bus via GPIO lines and expose it to
userspace without rebuilding the kernel. This is maily
intended to connect microcontrollers and other simple
SPI devices without making an ad-hoc kernel driver.
