How to submit patches?

[Daniel Ng]

Hi,

What are the current requirements for submitting a patch?

I have created a patch which provides an SPI_LSB_FIRST option for the
SPI Bit-banging driver.

The SPI Bit-banging driver currently only supports MSB-first data
transmission (see include/linux/spi/spi_bitbang.h).

If someone could point me to the relevant, current documentation for
submitting kernel driver patches, I'd be most appreciative.

Cheers,
Daniel
